ANATOMY

Detailed explanation-1: -B cells are generated and develop in the specialized microenvironment of the bone marrow, while the thymus provides a specialized and architecturally organized microenvironment for the development of T cells.

Detailed explanation-2: -B-cells and T-cells are also called lymphocytes. There are primary and secondary organs involved in the complex development of lymphocytes but, in most cases, B-and T-lymphocytes are the generated in bone marrow and in the thymus.

Detailed explanation-3: -Both B and T lymphocytes originate in the bone marrow but only B lymphocytes mature there; T lymphocytes migrate to the thymus to undergo their maturation. Thus B lymphocytes are so-called because they are bone marrow derived, and T lymphocytes because they are thymus derived.

Detailed explanation-4: -They develop from hematopoietic stem cells, which are produced in our bone marrow.

Detailed explanation-5: -A type of immune cell that is made in the bone marrow and is found in the blood and in lymph tissue. The two main types of lymphocytes are B lymphocytes and T lymphocytes. B lymphocytes make antibodies, and T lymphocytes help kill tumor cells and help control immune responses.
