The largest lymphatic organ in the body is the spleen
The spleen is the largest lymphatic organ in the body. The spleen is located on your left side, under your ribs, and above the stomach. It serves as a filter and stores blood too. The spleen is responsible for producing white blood cells that defend the body and fight infection.
Thanks to the spleen, old and damaged blood is replaced by fresh ones. The spleen measures a size of 12cm or five inches. It also produces lymphocytes.
