Organs of Immune System

 

All leukocytes are produced and mature in the bone marrow, except T lymphocytes, that mature in the thymus*. Mature leukocytes circulate constantly between the lymph nodes* and the spleen through blood vessels and lymphatic vessels.

*Thymus: organs located in the chest, at the basic of the strenum. 

*lymph nodes: small organs of the lymphatic network in which immune responses take place.

*Spleen: organ located in the upper left part of the abdomen (Dakroub, 2011).
