IMMUNOLOGY

Detailed explanation-1: -T lymphocytes develop from a common lymphoid progenitor in the bone marrow that also gives rise to B lymphocytes, but those progeny destined to give rise to T cells leave the bone marrow and migrate to the thymus (see Fig. 7.2). This is the reason they are called thymus-dependent (T) lymphocytes or T cells.

Detailed explanation-2: -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-3: -The primary parts of the immune system include the bone marrow and thymus. The bone marrow is extremely important to the immune system because all the body’s blood cells (including T and B lymphocytes) originate in the bone marrow. B lymphocytes remain in the marrow to mature, while T lymphocytes travel to the thymus.

Detailed explanation-4: -B lymphocytes mature in the bone marrow whereas T lymphocytes are produced in the bone marrow but mature in the thymus gland. Both the lymphocytes recognize and destroy any pathogen that enters the bloodstream.

Detailed explanation-5: -Thymus Cells Thymocytes are also called T-lymphocytes or T cells, and they begin as stem cells in bone marrow. They reach the thymus through the bloodstream. Thymopoiesis is the process where T cells mature into cells that can fight off foreign bodies but not attack the body’s own structure and processes.
