Which organ receives immature white blood cells, then raises them to maturity-and then releases them?
A
thymus
B
heart
C
lungs
D
brain
Explanation: 

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: -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.

Detailed explanation-3: -Inside the bone marrow, blood stem cells divide and mature to make new blood cells. During this process, the cells become either lymphocytes (a kind of white blood cell) or other blood-forming cells. These other blood-forming cells mature into red blood cells, white blood cells (other than lymphocytes), or platelets.

Detailed explanation-4: -Thymosin: The Hormone of the Thymus Thymosin stimulates the development of T cells. Throughout your childhood years, white blood cells called lymphocytes pass through the thymus, where they are transformed into T cells.
