- The main function of the immune system is defense against microbial infection. The other major functions of the immune system depend on a number of major actions that defend us against threats to our health.These actions help our immune system sort out a system of complicated reactions that our body uses every day to defend us from infection and disease.he other major functions of the immune system depend on a number of major actions that defend us against threats to our health.

Immune and Circulatory System Without cells from the immune system to fight off disease, the circulatory system wouldn't have these supportive cells to spreade through the body. Circulatory System. The organs of the circulatory system include the heart, blood/blood vessels, and lungs. Their functions are: Heart-Pump and circulate blood through the whole body. Lungs-Transport oxygen into the bloodstream and release carbon dioxide. Blood/Blood Vessels-Fluid that transports substances that are necessary for the body, such as nutrients and oxygen. Immune System.

- 1 Thymus. 2  The thymus gland is the main organ of the lymphatic system. 3  Its primary function is to promote the development of specific cells of the immune system called T-lymphocytes. 4  Once mature, these cells leave the thymus and are transported via blood vessels to the lymph nodes and spleen.he primary functions of the lymphatic system are to drain and return interstitial fluid to the blood, to absorb and return lipids from the digestive system to the blood, and to filter fluid of pathogens, damaged cells, cellular debris, and cancerous cells.

- In a broad sense, your immune system helps you fight disease. There are two parts to the immune system: Non-specific immunity + Specific immunity. Nonspecific immunity Consist … s of your skin, saliva, mucus, etc.Skin is the most important part in keeping diseases from entering your body. Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. Antibodies are proteins produced by the body to neutralize or … destroy toxins or disease-carrying organisms.

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.

Immune system The immune system is the set of tissues which work together to resist infections. The immune mechanisms help an organism identify a pathogen, and neutralize its threat. The immune system can detect and identify many different kinds of disease agents. Examples are viruses, bacteria and parasites.

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.

- What the immune system does. The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is really a collection of reactions and responses that the body makes to damaged cells or infection. So it is sometimes called the immune response.he white blood cells involved in the acquired immune response are called lymphocytes. There are two main types of lymphocytes – B cells and T cells. B and T lymphocytes are made in the bone marrow, like the other blood cells.

Drug Strategies to Target HIV: Enzyme Kinetics and Enzyme Inhibitors The immune system is a collection of cells found in the blood and in tissues throughout the body that help to protect the body from infection. These cells perform a variety of nonspecific and specific functions to defend the body against harmful particles (e.g. , bacteria, viruses, toxins, and cancerous cells).

- The immune system is a network of cells, tissues, and organs that work together to protect the body from infection. Why Is Immune System Research a Priority for NIAID? Although scientists have learned much about the immune system, they continue to study how the body targets invading microbes, infected cells, and tumors while ignoring healthy tissues.

How do the various T cells function in the immune system? Lymphocytes are different from other types of white blood cells because they recognize and remember invading bacteria and viruses. T lymphocytes, or T cells, are responsible for cell-mediated immunity. T cells come in many types with specific functions, including: 1  Helper T cells direct the immune system. 2  Cytotoxic T cells release certain chemicals that break open to kill invading organisms. 3  Memory T cells remain after this process to help the immune system respond more quickly when the same organism is encountered again. 4  Suppressor T cells do ...

Immune system The immune system is a system of many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue.nflammation is one of the first responses of the immune system to infection. The symptoms of inflammation are redness, swelling, heat, and pain, which are caused by increased blood flow into tissue. Inflammation is produced by eicosanoids and cytokines, which are released by injured or infected cells.

Stress, Illness and the Immune System The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs, defending the body against foreign bodies (antigens), such as bacteria, viruses and cancerous cells. There are two types of lymphocytes : B cells-produce antibodies which are released into the fluid surrounding the body’s cells to destroy the invading viruses and bacteria. T cells (see picture opposite) - if the invader gets inside a cell, these (T cells) lock on to the infected cell, multiply and destroy it.

LYMPHATIC SYSTEM AND IMMUNITY. The lymphatic system is composed of lymph vessels, lymph nodes, and organs. The functions of this system include the absorbtion of excess fluid and its return to the blood stream, absorption of fat (in the villi of the small intestine) and the immune system function.ntigens are chemicals on the surface of a cell. All cells have these. The immune system checks cells and identifies them as self or non-self. Antibodies are proteins produced by certain lymphocytes in response to a specific antigen.
