AP BIOLOGY

Detailed explanation-1: -The primary function of the thymus gland is to train special white blood cells called T-lymphocytes or T-cells. White blood cells (lymphocytes) travel from your bone marrow to your thymus. The lymphocytes mature and become specialized T-cells in your thymus. After the T-cells have matured, they enter your bloodstream.

Detailed explanation-2: -Precursors of T cells migrate from the bone marrow and mature in the thymus.

Detailed explanation-3: -Special types of immune system cells called thymus cell lymphocytes (T cells) mature in the thymus. Among other tasks, these cells coordinate the processes of the innate and adaptive immune systems. T cells move through the body and constantly monitor the surfaces of all cells for changes.

Detailed explanation-4: -Both originate from stem cells in the bone marrow and are initially similar in appearance. Some lymphocytes migrate to the thymus, where they mature into T cells; others remain in the bone marrow, where-in humans-they develop into B cells.

Detailed explanation-5: -T cells migrate from the bone marrow to the thymus, a small gland located in the neck. Here, they mature and differentiate into different types of T cells, such as CD8+ T cells and CD4+ T cells.
