MICROANATOMY

Detailed explanation-1: -The thymus is the organ primarily responsible for the production and maturation of T cells, functioning as the initial site of T cell immune maturation through positive and negative selection processes. T cells are so named as they mature in the thymus and B cells are named thus, as they mature in the bone marrow.

Detailed explanation-2: -T cells develop in the thymus from precursor cells that migrate there from the hemopoietic tissues via the blood.

Detailed explanation-3: -Precursors of T cells migrate from the bone marrow and mature in the thymus. This process is similar to that for B cells, including the sequential rearrangement of antigen receptor gene segments.

Detailed explanation-4: -The thymus makes white blood cells called T lymphocytes. These are also called T cells. These are an important part of the body’s immune system, which helps to fight infection. The thymus gland grows to its largest size during childhood and makes all the T cells we need before we become teenagers.
