The beautiful immune system lesson 5: The fundamental aspects of adaptive immune responses

As stated in lesson 4, adaptive immune responses to foreign antigens are made up of cell-mediated and humoral processes. The lymphocytes that carry out these processes (T cells for cell-mediated and B-cells for humoral) have fundamental properties that are essential for proper immune system function. 

And here they are:

When our bodies become sick with a virus, bacteria, fungi, parasite, etc., our adaptive immune system, the one that “remembers” microbes, not only fights off the microbe but creates protective immunity against it.

Protective immunity is the body’s ability to resist a certain disease. The body’s source of protective immunity against microbes comes from the antibodies created by B cells, as well as the memories stored in the body’s specialized lymphocytes (B and T cells). By “specialized”, I mean they hold a special memory of the particular microbe the protective immunity is against.
