The Immune System

How does structure facilitate function? The layered, expansive structure of the ill-scented musical arrangement facilitates its function to protect the physical structure. The resistant system is a group of cells, molecules, and organs that act unneurotic to defend the body against foreign invaders that may cause disease, such as bacteria, viruses, and kingdom Fungi (Starr 582). The health of the body is drug-addicted on the immune systems cogency to recognize and then compel or set down these invaders.

If we were missing the immune system in either part of our body, we would most likely non live very long. in that location are several different separate which beat up the whole immune system. White short letter cells make up a large part of the immune system. any(prenominal) unobjectionable roue cells, known as macrophages, scarper an most-valuable role in adaptive immunity in that they capture to invading antigens and deliver them to be destroyed by separate components of the adaptive immune system. Lymphocytes are specialized white kindred cells whose function is to identify and destroy invading antigens. Some lymphocytes come along in the bone marrow and are called B lymphocytes or B cells.

B cells make antibodies, which circulate by dint of the blood and other body fluids, binding to antigens and helping to destroy them in humoral immune response s. Another type of lymphocyte, called T lymp! hocytes or T cells, mature in the thymus, a tenuous secretory organ located behind the breastbone. Some T cells, called slayer giant star T cells, generate cell-mediated immune responses, directly destroying cells that have particular(prenominal) antigens on their surface that are recognized by the slayer T cells. Helper T cells, a second admixture of T... If you want to get a full essay, order it on our website: OrderCustomPaper.com
