The immune system has several functions such as defense against foreign organisms, homeostasis, and the destruction of damaged cells and surveillance. 24, 25 There are two types of immune responses: innate or nonspecific immunity and adaptive or specific immunity.

What the immune system does. The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is a collection of reactions and responses that the body makes to damaged cells or infection. So it is sometimes called the immune response.

New technologies may help immune cells identify cancer cells using tags on their inside or out. The immune system is the bodys main level of defense against a hostile world. From viruses and bacteria to the bodies own sick and dying cells, immune cells search out and destroy the troublemakers. The molecules that would otherwise reveal the cancer to the immune system are lost, and killer T cells move past, unaware of the danger the cancer cell could cause. Thats a surefire way of escaping detection, says Elliott, adding that its one of many escape methods cancer cells use. immune system and cancer cells Oct 19, 2017  At the same time, though, scientists are learning how cancer cells not only evade the immune systems defenses, but actually use immune cells to facilitate their attack on the body. Military precision. In military terms, the immune system has two divisions: innate and acquired.
