Immunology can be a very dangerous field for a person with no antibodies. Immunologists often times deal with microbiological cultures and possibly biohazard cultures as well. Very often times are an immunologist associated with a Allergist because they deal with the reaction and rejection of the body to foreign micro

tissues. This network aids in the removal of waste and unwanted products from the body. The lymphatic system’s most important function is to transport white blood cells that fight infection called lymph though the body. These white blood cells contain antibodies which are built to detect‚ destroy and build immunity towards pathogens and infections that enter the body. The lymphatic system consists of lymphatic vessels‚ lymphatic organs and lymph. Lymphatic Vessels Lymphatic vessels are tubes with thick

Antibodies‚ are better known as immunoglobulins‚ they are a Y-shaped proteins that are formed by the immune system to stop invaders from hurting the body (What Are Antibodies? - Definition‚ Function & Types‚ n.d.).

An autoimmune disorder is when the body in essence attacks itself. 10. Tissue grafts taken from unrelated persons are called allografts. 11. Small proteins that diffuse to nearby cells and bind to their membrane receptors are called interferons. 12. Antibodies are also referred to as immunoglobulins or IGS and constitute the gamma globulin
