- Tonsils is the first line of defense in the oral cavity
- Thymus is the organ where lymphocytes are developed
- Red bone marrow is where special lymphocytes are produced
The tonsils, which are located in the throat, work with the immune system to filter and collect pathogens. Particularly during childhood and adolescence, the thymus, a gland located in the chest, is essential for the maturation of T lymphocytes that are necessary for adaptive immunity.
Hematopoiesis, the process that produces red and white blood cells as well as platelets, is carried out by red bone marrow, which is located within bones like the sternum and pelvis. When combined, these elements support the body's immune system and blood cell production, which are vital for overall health.
