The roles of T cells and B cells in adaptive immunity.

Introduction:

The immune system is defined as the group of cells or tissues or organs that functions against the foreign substance to provide the immunity. The immunity is classified into two categories, innate and adaptive.

Immunoglobulins are produced by plasma cells, which contain the antigen binding site that allow the antigen to bind. They are found in blood, tissues and other body fluids to make the immune system.

Antibodies and lymphocytes are the major elements in the adaptive immune system. The lymphocytes consist of B cells, cytotoxic T cells and Helper T cells which are involved in the adaptive immune response against the infectious pathogens.
