The spleen is an organ of the lymphatic system located on the left side of your stomach (abdomen) under the rib cage and diaphragm in a region that is referred to as the left upper quadrant. In humans the spleen is about the size of a fist and its primary roles are filtering the body’s blood and helps to fight infection. It also serves a role in storing and releasing certain types of immune cells that mediate tissue inflammation. [1]Rupturing a spleen describes an emergency situation in which your spleen has developed a disruption in its surface or blood supply. This is serious condition that can occur during a direct blow or trauma and without emergency treatment a ruptured spleen can cause life threatening internal bleeding. [2]
