What Does the Spleen Do?
Reviewed: Dr. Gromatzky
3. Stores Blood
The spleen has an intricate network of blood vessels that can expand to accommodate more blood. Studies show that the spleen stores about eight ounces of blood. This blood is held as reserve for when it may be required within the body; for instance, following an injury that causes a significant loss of blood.
Additionally, the spleen stores platelets. These are blood components that are necessary for blood clotting, which is necessary for stopping loss of blood resulting from injury. It is also worth noting that in the spleen’s blood reserve are white blood cells whose role includes fighting infection.
