The spleen is the largest organ of the lymphatic system. Its primary function is to filter the blood of damaged cells, cellular debris, and pathogens. Like the thymus, the spleen houses and aids in the maturation of lymphocytes. Lymphocytes destroy pathogens and dead cells in the blood. The ...

One of the unique features of the immune system is that its constituent cells are not fixed in a single organ; they move throughout the body to various locations in order to carry out their work efficiently. Although leukocytes circulate in the blood, it is within the tissues that the servi...
The design of lymphatic delivery systems ranges from simple systems that rely on passive lymphatic access to more complex structures that integrate into endogenous lymph transport processes. Recent studies have suggested the presence of active transport processes that facilitate entry across the lymphatic ...
The abdomen is also the site of the largest secondary lymphoid organ, the spleen. This spleen is seen in the left hypochondrium, wedged between the diaphragm and the stomach. It is directed downwards, forwards and laterally along the long axis of the 10th rib. Its hilum is cl...
