Summary Introduction
Introduction:
The immune system can be defined as the organs and body processes that resist the infection and toxins. This system includes the organs such as bone marrow, thymus, and lymph nodes. Lymphocytes are of two types: B cells and T cells. B cells play a role in cellular immunity. T cells help in the antibody/humoral immunity. These exist throughout the body.
