Spleen
From Conservapedia
The spleen is an organ above the stomach and under the ribs on the human body's left side. It is about as big as a human's fist. The spleen is part of thelymphatic system, which fights infection and keeps body fluids in balance. The spleen contains white blood cells that fight germs, and also helps control the amount of blood in the body, and destroys old and damaged cells.
Certain diseases might cause the spleen to swell. If the spleen is too damaged, in some cases surgically removing it is necessary.Other organs, such as the liver, will take over some of the spleen's work; however, the body will lose some of its ability to fight infections.[1]
