The Spleen – A Comprehensive Guide

The spleen is an organ located in the upper left side of the abdomen, playing a key role in your immune system and blood health. It filters your blood, removing old or damaged red blood cells and bloodborne pathogens. The spleen also helps store healthy blood cells and produces certain immune cells to fight infections. While not essential for survival, it supports your body's ability to respond to illness. If the spleen becomes damaged or enlarged, medical attention may be needed. Overall, it’s a vital part of maintaining healthy blood and immune function.
