Explain various types of blood cells Class 9

There are three type of blood cells :-1) red blood cell 2) white blood cell 3) platelets red blood cell:- function:-1 transport oxygen from lungs to the cell of the body 2 pick up carbon dioxide from other tissues and unload it in the lungs white blood cell:- enters the tissue where they become larger and turn into Macrophage There are five main types of WBCs.: Neutrophils (granulocytes), Eosinophils (granulocytes), Basophils (granulocytes), Lymphocytes (non-granulocytes) and Monocytes (non-granulocytes) Blood contains three different types of blood cells, namely, red blood cell (erythrocytes), white blood cell (leukocytes), and platelets. In turn, there are three types of white blood cells—lymphocytes, monocytes, and granulocytes—and three main types of granulocytes (neutrophils, eosinophils, and basophils) There various types of white blood cells are neutrophils, B lymphocytes, T lymphocytes, monocytes, basophils and eosinophils 9. Where are the red blood cells produced? The red blood cells are produced in the bone marrow

There are four major blood groups determined by the presence or absence of two antigens - A and B - on the surface of red blood cells. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (-), creating the 8 most common blood types (A+, A-, B+, B-, O+, O-, AB+, AB-) A complete blood count (CBC) test gives your doctor important information about the types and numbers of cells in your blood, especially the red blood cells and their percentage (hematocrit) or protein content (hemoglobin), white blood cells, and platelets. The results of a CBC may diagnose conditions like anemia, infection, and other disorders.The platelet count and plasma clotting tests. Blood types depend on the content of the blood cells and are inherited from parents. There are eight main types. Which type you have affects how you can receive blood Connective Tissue. They are specialised to connect various body parts. For Ex:Bone to bone,Muscle to bone or tissue. The main function is binding ,supporting and packing together different organs of body. The cells of connective tissue are living, separated from each other and are very less in number.Homogeneous gel like intercellular substance. Multipotent Stem Cells: These differentiate into a closely related cell type. For eg., the hematopoietic stem cells differentiate into red blood cells and white blood cells. Oligopotent Stem Cells: Adult lymphoid or myeloid cells are oligopotent. They can differentiate into a few different types of cells. Unipotent Stem Cells: They can produce.

White Blood Cells. White blood cells, also called leukocytes, are much fewer in number than red blood cells. There are 5 different types of white blood cells that collaborate to protect the body by attacking foreign intruders, consisting of bacteria, viruses and tumors. The most typical type of white blood cells are called neutrophils Blood is the unique fluid connective tissue present in our body and it plays a significant role in transporting a wide variety of substances to different parts of the body. The main components of blood include Red blood cells, White blood cells, blood platelets and plasma There are five different types of white blood cells, each of which has a different funtions in the immune system. Five White Blood Cells Types and Their Functions. There are two different kinds of white blood cells and each looks different from one another under the microscope. These include granulocytes and agranulocytes

Complex tissues are of two types: Xylem or wood and phloem or bast. Xylem and phloem are both conducting tissues and also known as vascular tissues; together both them constitute vascular bundles. Xylem: Xylem is a vascular and mechanical tissue. Xylem is composed of cells of four different types: 1. Tracheids 2 Class 9 Biology Tissues. Connective Tissues. CONNECTIVE TISSUES. It protects and supports the body. The cells are loosely spaced and embedded in an intercellular matrix. The matrix may be jelly like, fluid, dense or rigid. The nature of matrix differs in concordance with the function of the particular connective tissue. AREOLAR NCERT Solutions For Class 9. NCERT Solutions For Class 9 Social Science; There are more than hundred different types of cancer that are characterized by abnormal cell growth. These abnormal white blood cells damage the tissues of the bone marrow and crowd the normal blood cells

Formation. Elevated White Blood Cell Counts. Low White Blood Cell Counts. White blood cells (WBCs) are a part of the immune system that helps fight infection and defend the body against other foreign materials. Different types of white blood cells are involved in recognizing intruders, killing harmful bacteria, and creating antibodies to. Recall that blood is a connective tissue. Like all connective tissues, it is made up of cellular elements and an extracellular matrix. The cellular elements—referred to as the formed elements—include red blood cells (RBCs), white blood cells (WBCs), and cell fragments called platelets.The extracellular matrix, called plasma, makes blood unique among connective tissues because it is fluid It is composed of plasma and different types of cells. Blood constitutes different type of corpuscles in it. They are known red blood corpuscles, leukocytes and thrombocytes. For those who want to know how many types of blood groups in human body: Red blood cells constitute 45 % of blood; plasma is about 54.3% and leukocytes of 0.7% Types of Epithelial Tissue: Classification of epithelial tissue is mainly based on their layers, shape and functioning. 1. Classification Based on Their Shape: a. Squamous Epithelium: This type of tissue has cells with wider length than their height. They are mainly found as the lining of the mouth, oesophagus, alveoli of lungs including blood.

There are different types of white blood cell, and each has a specific function in the body. Certain conditions can affect the number of white blood cells in the body, causing them to be too high. Blood transports digested food to different cells of the body. Transport of waste products : Blood transports the waste products of cells and organs to the kidneys, lungs, skin and intestine, so that they may be eliminated. Chemical coordination : Hormones produced by endocrine glands are distributed to the vital tissues by the blood Question 9. Describe the types of connective tissues along with their functions. Answer: There are five types of connective tissues: (i) Areolar connective tissue: It is a loose and cellular connective tissue.

The cell is the basic and structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life. Cells are called the building blocks of life. The study of cells is called cell biology. Learn about Nucleus Structure and Function, Cell Nucleus, Nuclear Membrane at Vedantu.co Inflammation is a process by which your body's white blood cells and the things they make protect you from infection from outside invaders, such as bacteria and viruses. But in some diseases, like. Different Types of Blood Cells and Their Roles in the Human Body Blood is a mixture of two things: cells and plasma. The heart pumps blood through the arteries, capillaries and veins to provide oxygen and nutrients to every cell of the body. The blood also carries away waste products The average human adult has more than 5 liters (6 quarts) of blood in his or her body. Blood carries oxygen and nutrients to living cells and takes away their waste products. It also delivers immune cells to fight infections and contains platelets that can form a plug in a damaged blood vessel to prevent blood loss In humans, the surface glycoproteins and glycolipids on red blood cells vary between individuals, producing the different blood types, such as A, B, and O. Red blood cells have an average life span of 120 days, at which time they are broken down and recycled in the liver and spleen by phagocytic macrophages, a type of white blood cell

It is present in all plant cells .It is somehow different from cell membrane in many aspects as it is listed below . Class 9th English Lessons
  6. Blood cells are made in the bone marrow by blood 'stem' cells. Blood cells are divided into three main types: Red cells (erythrocytes). These make blood a red colour. One drop of blood contains about five million red cells. A constant new supply of red blood cells is needed to replace old cells that break down. Millions of red blood cells are.

A complex tissue is made up of more than one type of cells. In blood, cells of different types, colour and shapes are mixed together. Blood contains erythrocytes (RBCs), leucocytes (WBCs) and platelets in a liquid plasma. Therefore, blood is a complex tissue. Define the following: Question 1. Tissue Answer 4. An important concept in biology is that form follows function. In other words, the structure of an organism, or part of an organism, depends on its function. Apply this concept to plants, and explain why plants have different types of cells and tissues White blood cells (WBC) are a heterogeneous group of nucleated cells that can be found in circulation for at least a period of their life. Their normal concentration in blood varies between 4000 and 10,000 per microliter. They play a most important role in phagocytosis and immunity and therefore in defense against infection View final paper 2 class 9 (1).docx from BIO 5090 at Beaconhouse School System. 1 Table 1.1 shows the masses of various substances in 100 g of banana fruit and in 100 g of avocado fruit. Table 1.

Different types of blood vessels vary slightly in their structures, but they share the same general features. Arteries and arterioles have thicker walls than veins and venules because they are closer to the heart and receive blood that is surging at a far greater pressure (Figure 20.1.2) White blood cells: White blood cells (WBCs, also called leukocytes, say: LOO-kuh-sytes) are a key part of the immune system. The immune system helps the body defend itself against infection. Different types of WBCs fight germs, such as bacteria and viruses. Some types of WBCs make antibodies, which are special proteins that recognize foreign. Adult hematopoietic stem cells, for example, can become red and white blood cells or platelets. Oligopotent: These can differentiate into a few different cell types. Adult lymphoid or myeloid stem. The total number of leukocytes and percentages of different leukocytes in the human peripheral blood are given in Table 4.1. There are different types of leukocytes: 1. Lymphocytes: Lymphocytes arise from the hematopoietic stem cells in the bone marrow. The normal adult human has about trillion (10 12) lymphocytes

Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body. Until recently, researchers thought adult stem cells could create only similar types of cells. For instance, researchers thought that stem cells residing in the bone marrow could give rise only to blood cells Use of immobilized cells for fermentation is a very old practice. Bacteria or yeast cells are immobilized by adsorbing it on woodchips. This is practiced in many parts for different types of fermentations. Advantages of whole cell immobilization: (a). Multiple enzymes can be introduced to a single step (b) Science Class 11 Biology (India) different components plasma proteins among other things and the cellular components of our blood which are red blood cells white blood cells and platelets are all formed within the bone marrow of our bones and so those are the main functions of the bones that form our skeleton now one way of classifying. Within blood, there are substances called antibodies which distinguish particular antigens from others, causing bursting or agglutination of the red cells when alien antigens are found. The antibodies bind to the antigens. In the case of agglutination, the antibodies glue together the antigens from different red cells thereby sticking the red cells together (as shown below on the right) Answer: Cough, cold, loose motions, pain in abdomen, headache, wound with pus, continuous pain in some body part, breathlessness, loss of body weight, feeling of tiredness. Each symptom can be due to many reasons. Only a doctor can diagnose the ailment and prescribe proper treatment. Question 19


Blood cells and its types with function

  1. Nervous tissue is the term for groups of organized cells in the nervous system, which is the organ system that controls the movements of the body, sends and transmits signals to and from different parts of the body, and plays a role in controlling the functions of the body, such as digestion
  2. It is a limited space where all the different types of blood cells are made and where nutrients and other resources are supplied to help these cells grow. Blood cells keep our body healthy and functioning normally. More specifically, the different types of blood cells produced in the bone marrow include: Red blood cells
  3. Blood makes up about 8% of the human body weight. It contains erythrocytes, leucocytes, thrombocytes (platelets) and plasma.. The volume percentage of all blood cells in the whole blood is about 45% of adults (hematocrit). The rest consists of liquid plasma (e.g. water, plasma proteins, electrolytes etc.)
  4. The next type of blood cell is the leukocyte, also known as white blood cells or WBCs. These are members of our body's defense team since they protect us from invading bacteria and other pathogens

Common Causes for Various Types of Anemia 1.) Hypochromic, microcytic: Iron Deficiency Thalassemia syndromes Sideroblastic anemia Transferrin deficiency. Red blood cells. These cells carry oxygen to the tissues in the body and are commonly used in the treatment of anemia. Platelets. They help the blood to clot and are used in the treatment of leukemia and other forms of cancer. White blood cells. These cells help to fight infection, and aid in the immune process. Plasma WBC (white blood cell) differential count. This test measures the numbers, shapes, and sizes of various types of white blood cells listed above. The WBC differential count also shows if the numbers of different cells are in proper proportion to each other. Irregularities in this test could signal an infection, inflammation, autoimmune disorders.


Blood types: What are they and what do they mean

Susumu Nishinaga / Getty Images. There are four main types of blood vessels that each play their own role: Arteries: These are elastic vessels that transport blood away from the heart. Pulmonary arteries carry blood from the heart to the lungs where oxygen is picked up by red blood cells.Systemic arteries deliver blood to the rest of the body Cytotoxic T cells (CD8+) Cytotoxic T cells (Tc cells) have a co-receptor called CD8 on their cell surface. CD8 partners with the T cell receptor and with MHC class I molecules, acting as a sort of bridge.This bridge allows cytotoxic T cells to recognize normal cells that are infected by a pathogen.When the cytotoxic T cell recognizes the infected cell, it becomes activated and produces. Blood type (also called blood group) is a classification of blood based on the presence or absence of inherited antigenic substances (antigens) on the surface of red blood cells. If the red blood cell had only A antigen on it, that blood was called type A. If the red blood cell had only B antigen on it, that blood was called type B

The cells that leave the thymus become single positives, expressing either CD4 or CD8, but not both. The CD4 + T cells will bind to class II MHC and the CD8 + cells will bind to class I MHC. The discussion that follows explains the functions of these molecules and how they can be used to differentiate between the different T cell functional types ABO blood group system, the classification of human blood based on the inherited properties of red blood cells (erythrocytes) as determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells. Persons may thus have type A, type B, type O, or type AB blood. The A, B, and O blood groups were first identified by Austrian immunologist Karl.

Differences Between Blood and Lymph - Major differences

Like red blood cells, every part of the body is composed of different types of cells. According to cell theory, all of these cells are derived from the zygote, which is a single cell that results from the fertilization of an egg with a sperm. This cell then divides, replicates, and begins to differentiate into the many different cell types of the body Red blood cells, also called erythrocytes, are the most abundant cell type in the blood. Other major blood components include plasma, white blood cells, and platelets. The primary function of red blood cells is to transport oxygen to body cells and deliver carbon dioxide to the lungs. A red blood cell has what is known as a biconcave shape When you read about antigen and antibody, you will begin to understand that these have something to do with the immunity in the body. In the field of microbiology and immunology, the antigen-antibody complex has a major role. Let us take a detailed look Blood The composition of blood. Blood transports materials and distributes heat around the body. It also helps to protect against disease. Blood contains plasma, which is a liquid that the other.

5 White Blood Cells Types and Their Functions New Health

Small, specialised white blood cells with large nuclei and no granules. normally make up 20-45% of all white blood cells (1.3-3.5 x 10 9 /L on a full blood count) there are three main subtypes of lymphocytes: B cells, T cells and natural killer (NK) cells; B cells and T cells make up the majority of the lymphocyte population. They are small. Multiple myeloma is a cancer that forms in a type of white blood cell called a plasma cell. Healthy plasma cells help you fight infections by making antibodies that recognize and attack germs. In multiple myeloma, cancerous plasma cells accumulate in the bone marrow and crowd out healthy blood cells The cells of the tissue can take up different shapes to become specialized and perform specific functions. And so, epithelial tissues have cells that have different shapes, sizes, and arrangements. Accordingly, they are classified into different types. Epithelial cells can be seen in different parts of the body Lab 2: Microscopy and the Study of Tissues. 1. Introduction to histology (Part 1) Tissues are composed of similar types of cells that work in a coordinated fashion to perform a common task, and the study of the tissue level of biological organization is histology. Four basic types of tissues are found in animals

Detailed Tissues class 9 notes (NCERT book chapter 6

Platelets, also known as thrombocytes, are blood cells responsible for blood clotting. If a blood vessel wall becomes damaged, platelets will rush to the site of injury and form a plug or clot to stop the bleeding. If platelet count is low (a condition called thrombocytopenia), the risk of uncontrolled or prolonged bleeding increases The types are: 1. Innate (Natural or Nonspecific) Immunity 2. Acquired (Specific or Adaptive) Immunity 3. Active and Passive Immunity. Type # 1. Innate (Natural or Nonspecific) Immunity: Innate immunity (also called nonspecific or natural immunity) refers to the inborn-ability of the body to resist, and is genetically transmitted from one. Onion Cell. An onion is a multicellular (consisting of many cells) plant organism. As in all plant cells, the cell of an onion peel consists of a cell wall, cell membrane, cytoplasm, nucleus and a large vacuole. The nucleus is present at the periphery of the cytoplasm. The vacuole is prominent and present at the centre of the cell bird red blood cells (shown to the right), unlike those of mammals, are elliptical in shape and nucleated. In most species, red blood cells are about 6 x 12 microns in size (mammalian RBC's are typically 5.5 - 7.5 microns in diameter). Typical concentrations are 2.5 to 4 million/cubic mm. Avian red blood cells have a lifespan of 28-45 days. Immuno describes immunity and globulin describes protein. 2  They are produced by B cells, a specific type of white blood cell (WBC) that originates in the bone marrow. While there are only five main types of antibodies, each antibody can have a different binding site that matches a specific antigen

Programmed cell death (PCD; sometimes referred to as cellular suicide) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy. PCD is carried out in a biological process, which usually confers advantage during an organism's lifecycle.For example, the differentiation of fingers and toes in a developing human embryo occurs because cells between the fingers. The human leukocyte antigen (HLA) system or complex is a complex of genes on chromosome 6 in humans which encode cell-surface proteins responsible for the regulation of the immune system. The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals.. Mutations in HLA genes may be linked to autoimmune disease such as type I diabetes, and. Types of Antigen On the basis of order of their class (Origin) 1. Exogenous antigens. These antigens enters the body or system and start circulating in the body fluids and trapped by the APCs (Antigen processing cells such as macrophages, dendritic cells, etc.) The uptakes of these exogenous antigens by APCs are mainly mediated by the phagocytosi Cells in the human body number in the trillions and come in all shapes and sizes. These tiny structures are the basic unit of living organisms. Cells comprise tissues, tissues make up organs, organs form organ systems, and organ systems work together to create an organism and keep it alive..

Types of Cancer - Symptoms, Causes and Treatmen

Answer: B. The Role of Glucagon. Glucagon, a peptide hormone secreted by the pancreas, raises blood glucose levels.Its effect is opposite to insulin, which lowers blood glucose levels. When it reaches the liver, glucagon stimulates glycolysis, the breakdown of glycogen, and the export of glucose into the circulation.In these ways, the effects of glucagon are catabolic, breaking down cells. Cancer growth blockers are also called cancer growth inhibitors. They are a type of targeted cancer drug. Our body makes chemicals called growth factors that control cell growth. Cancer growth blockers work by blocking the growth factors that trigger cancer cells to divide and grow Bone marrow is a soft connective tissue that produces blood cells. It is found inside the pores of spongy bone. Periosteum is a tough, fibrous membrane that covers and protects the outer surfaces of bone. This bone contains different types of bone tissue. How does each type of tissue contribute to the functions of bone

Types and Function of White Blood Cells (WBCs

As blood and tissue fluids circulate around the body, various components of the immune system are continually surveying for potential sources of attack or abnormal cells. Antigens and antibodies Antigens are usually either proteins or polysaccharides (long chains of sugar molecules that make up the cell wall of certain bacteria) 5) It is used for sedimentation of red blood cells until the particles are tightly packed into a pellet and supernatant is separated by decantation. HIGH-SPEED CENTRIFUGES High-speed centrifuges are used in more sophisticated biochemical applications, higher speeds and temperature control of the rotor chamber are essential Blood. 1. Areolar (loose) Connective Tissue. They are a loose array of random fibers that has a wide variety of cell type. In addition, they nourish and pillows epithelia.

The Two Types of Bone Marrow Bone Marrow Transplantation and Stem Cell Therapies are literally the heart of many clinical trials and research efforts. (1) Many people are struggling to survive and cope as they live with chronic diseases, blood disorders, and cancer. As a result, the s Cancer is a type of disease where cells grow out of control, divide and invade other tissues.In a person without cancer, cell division is under control. In most tissues, healthy cells divide in a controlled way and copy themselves to create new healthy cells.With cancer, this normal process of cell division goes out of control. Cells change their nature because mutations have occurred in their. Tissue Membranes. A tissue membrane is a thin layer or sheet of cells that either covers the outside of the body (e.g., skin), lines an internal body cavity (e.g., peritoneal cavity), lines a vessel (e.g., blood vessel), or lines a movable joint cavity (e.g., synovial joint). Two basic types of tissue membranes are recognized based on the primary tissue type composing each: connective tissue. Rarer types of leukemia. Among the many different types of leukemia, some are less common than others. Three rarer leukemia types—prolymphocytic leukemia (PLL), large granular lymphocyte leukemia (LGL) and hairy cell leukemia (HCL)—share some of the same characteristics as lymphocytic leukemias and are sometimes considered subtypes of chronic or acute lymphocytic leukemia (CLL and ALL) Micronutrients are one of the major groups of nutrients and vital for human health.
