- There are a number of cells that are able to take up foreign antigen and “present” it on their surface for the rest of the immune system to see – in particular, T-cells and B-cells. Cells that are particularly good at presenting antigen are: Dentritic cells, Macrophages and B-cells.

- There are four types of T cells, each with a special purpose. 1  Helper T cells detect infection and get the other cells of the immune system ready for battle. 2  Cytotoxic, or killer, T cells destroy infected cells. 3  Regulatory T cells tell the immune system when the battle with the pathogens is over and to stop fighting.

What Are the Three Kinds of Blood Cells? 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 work together to protect the body by attacking foreign invaders, including bacteria, viruses and tumors.hite Blood Cells.

The Immune System -- An Overview Reviewed October 2008. The immune system is composed of many interdependent cell types that collectively protect the body from bacterial, parasitic, fungal, viral infections and from the growth of tumor cells. Many of these cell types have specialized functions.

- There are two major cell types of immune system cells (1) phagocytes and (2) lymphocytes. Lymphocytes are small white cells found in lymphoid tissues and are also present in the blood. They get to the blood stream from the lymph nodes, which are small pea sized organs distributed throughout the body.

The Human Immune System and Infectious Disease Two types of white blood cells called lymphocytes are vital to the specific immune response. Lymphocytes are produced in the bone marrow, and mature into one of several subtypes. The two most common are T cells and B cells. An antigen is a foreign material that triggers a response from T and B cells.The human body has B and T cells specific to millions of different antigens. We usually think of antigens as part of microbes, but antigens can be present in other settings.pecific immunity is a complement to the function of phagocytes and other elements of the innate immune system. In contrast to innate immunity, specific immunity allows for a targeted response against a specific pathogen.

The Immune System: Information about Lymphocytes, Dendritic Cells, Macrophages, and White Blood Cells The Immune system is a complex network of cells (such as lymphocytes) and organs that work together to defend the body against foreign substances (antigens) such as bacteria, a virus or tumor cell. When the body discovers such a substance several kinds of cells go into action in what is called an immune response.

Types of Cells in the Body 2. Blood Cells. From transporting oxygen throughout the body to fighting infection, cells of the blood are vital to life. The three major types of cells in the blood are red blood cells, white blood cells, and platelets. Red blood cells determine blood type and are also responsible for transporting oxygen to cells.

Overview of Immunity The cells of the adaptive immune system are special types of leukocytes, called lymphocytes. B cells and T cells are the major types of lymphocytes and are derived from hematopoietic stem cells in the bone marrow.

When the body is invaded by antigens, the immune system forms substances called? Antibodies. A. k.a. immunoglobulins. They are produced by a group of white blood cells called B lymphocytes (or B cells). There are 5 classes of immunoglobulins; IgM,IgA,IgE,IgG and IgD.The classes of antibody diifferent both in their constant region and in their activity.IgG, the most common antibody, and is found mostly in the blood and tissue fluids, and IgA is localized in the mucous membranes which line the respiratory and gastrointestinal tracts.

Medical Terminology for Cancer There are many different cell types and sub-types involved in the immune system. Some of the main types include: Lymphocytes: are white cells which circulate between blood and lymph. They play an important role in fighting infection.

Chapter 3: Functions of the Immune System and Immunodefciency Diseases Name the functional components of the immune system. Antibodies, Lymphocytes, Lymphoid tissue, Macrophages. Describe the three major functions of the immune system. • Battle infection. • Maintains homeostasis by eliminating damaged cells. • Protects the body against foreign organisms.

The Immune System - in More Detail T cells. T cells come in two different types, helper cells and killer cells. They are named T cells after the thymus, an organ situated under the breastbone. T cells are produced in the bone marrow and later move to the thymus where they mature.

Infection 1 Infection fighting cells of the immune system: Particularly the white blood cells (WBC). 2  There are five main types of WBC's-lymphocytes (B and T cells), macrophages, basophils, eosinophils and neutrophils. 3  When your white blood cell count is low there is an increased risk of infection.

Blood cells - Part three - Granulocytes and monocytes Blood cells - Part three - Granulocytes and monocytes. This article, the third in a series on blood cells, describes two types of white blood cells: granulocytes and monocytes. These along with lymphocytes, which will be discussed in the next article in this series, are responsible for the immune response. VOL: 101, ISSUE: 42, PAGE NO: 26.

White Blood Cells 1 There are three main types of lymphocytes: T cells, B cells, and natural killer cells. 2  T cells and B cells are critical for specific immune responses. 3  Natural killer cells provide nonspecific immunity. 4  Monocytes-These cells are the largest of the white blood cells.

Here are the different types, names and classifications of white blood cells working inside your body right now: Leukocytes.

- The immune system is complex and pervasive. There are numerous cell types that either circulate throughout the body or reside in a particular tissue. Each cell type plays a unique role, with different ways of recognizing problems, communicating with other cells, and performing their functions.kin: The skin is usually the first line of defense against microbes. Skin cells produce and secrete important antimicrobial proteins, and immune cells can be found in specific layers of skin. Bone marrow: The bone marrow contains stems cells that can develop into a variety of cell types.

MADMAN BIOLOGY The immune system is made up of different types of cells and substances. White blood cells are the most important cells of the immune system. Different types of white blood cells (lymphocytes and granulocytes) work with other parts of the immune system in slightly different ways. The lymphatic system and other substances also play important roles in the immune system response.
