Detailed explanation-1: -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-2: -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.
Detailed explanation-3: -The tissues and organs that produce, store, and carry white blood cells that fight infections and other diseases. This system includes the bone marrow, spleen, thymus, lymph nodes, and lymphatic vessels (a network of thin tubes that carry lymph and white blood cells).
Detailed explanation-4: -Bone marrow makes stem cells, which produce platelets and white and red blood cells. Here’s why those cells are important to your child’s health. A bone marrow transplant (BMT) restores healthy bone marrow in children with stem cell defects, cancer and certain inherited diseases.
