Answer 2

White blood cells (lymphocytes) are the primary agents of the immune response. The various types are as follows:

1. B cells. These originate and mature in the bone marrow ( B for bone). They respond to antigen markers with their special antigen receptors (antibodies) on their surface. Antibodies inactivate antigens by binding to them. Inactivation is followed by phagocytosis. Also they stimulate complement proteins to bring about the lysis of pathogens. When a B cell eventually binds to an antigen, it can divide into:

a) Plasma cells which circulate through the blood

b) Memory cells to stay in the body

2. T Cells originate in the bone marrow but then transfer to the thymus gland ( t for thymus). They have receptors for recognizing self versus non self antigens. When a T cell encounters a nonself cell they can divide into two types of cells:

a) Cytotoxic (killer) T cells recognize and destroy nonself cells by exploding (lysing) them.

b) Helper T cells stimulate the production of B cells and Cytotoxic T cells.
