The spleen is an internal body organ in the abdomen just underneath the left rib cage. The purpose of the spleen is similar to a lymph node, but involves filtering of the blood (rather than lymph). The filtered material is also attacked and broken down. Humans can survive without a spleen, but are more vulnerable to infection.

Spleen: The spleen is an organ of the lymphatic system and immune system. It is the largest of the lymph organs and is located in the upper left abdominal area. It is made of lymphatic tissue that produces lymphocytes and also houses macrophages. These immune cells attack and remove pathogens from the blood to prevent infection. The spleen also filters out old red blood cells and recycles the iron from red blood cells for use as needed. It also stores monocytes.
Circulation to the spleen is through the splenic artery and splenic vein. It is innervated by the splenic plexus. The spleen contains both a white pulp and a red pulp. Conditions that can afflict the spleen include splenomegaly, ruptured spleen, trauma, leukemia, lymphomas, infections, and splenic vein obstruction.
