Instead, the spleen is connected to your blood vessels, with an artery that brings blood to it and a vein which takes the blood away. The spleen is composed of two types of tissues: the red pulp, which filters the blood, and the white pulp, which contains white blood cells that regulate inflammation and the body’s response to infection.

The loss of the spleen’s ability to filter out infected red blood cells increa...
