Immune System
The immune system is the organ system that protects an organism from outside biological influences. In the broad sense, almost every organ has a protective function (such as the skin). In the narrow sense, many higher organisms have organs dedicated to the maintenance of immunity, such as the thymus.It is often divided into the two sections of innate and adaptive immunity, the former encompassing unchanging mechanisms that are continuously in force to ward off noxious influences, and the latter responding to new influences by mounting an immune response. |
