ANATOMY

Detailed explanation-1: -The adaptive immune system is made up of: T lymphocytes in the tissue between the body’s cells. B lymphocytes, also found in the tissue between the body’s cells. Antibodies in the blood and other bodily fluids.

Detailed explanation-2: -T cells regulate the activities cells participating in immune responses. They provide help for antibody production by B cells, and they are also the effectors of antigen-specific cell-mediated immunity (CMI).

Detailed explanation-3: -T cells and B cells are the two major components of adaptive immunity.

Detailed explanation-4: -T cells are a part of the immune system that focuses on specific foreign particles. Rather than generically attack any antigens, T cells circulate until they encounter their specific antigen. As such, T cells play a critical part in immunity to foreign substances.

Detailed explanation-5: -The adaptive immune response in B cells, Helper T cells and Cytotoxic T cells involved four phases: encounter, activation, attack, and memory.
