What Is the Largest Lymphatic Organ?

The largest lymphatic organ in the human body is the spleen. The spleen is a purple vascular organ that is shaped like a fist. This organ is protected by the ribcage, and it is located between the stomach and the diaphragm in the abdomen.

The primary function of the spleen is to purify the blood and store blood cells. This organ helps the immune system identify and combat foreign antibodies. The spleen consists of white pulp and red pulp. The white pulp generates blood cells and synthesizes antibodies, and the red pulp removes old blood cells and filters the blood.
