Question 5

Briefly describe the actions of the body's phagocytes and lymphocytes.

Accepted Answer

Phagocytes are white blood cells that can ingest and destroy antigens. When a phagocyte recognizes a foreign particle, the phagocyte forms a pocket in its own outer membrane, engulfing the invader. Then the phagocytes may attack the invader with oxidative chemicals in an "oxidative burst" or may otherwise digest or destroy them. Phagocytes also leave a chemical trail that helps other immune cells to join the defence against infection. Lymphocytes are white blood cells that participate in the immune response. They are known as T-cells and B-cells. Killer T-cells recognize chemical messages from phagocytes and "read" and "remember" the identity of an invader from the messages. They then seek out and destroy all foreign particles with the same identity. B-cells respond rapidly to infection by dividing and releasing invader-fighting proteins-antibodies-into the bloodstream. Antibodies travel to the site of the infection and stick to the surface of the foreign particles, killing or inactivating them. Like T-cells, the B-cells also retain a chemical memory of each invader, and if the encounter recurs, the response is swift.
