Living Light: The Surprising Organs You Don't Actually Need
Your Spleen: The spleen sits in your upper left abdomen and helps filter blood and fight infections. While it plays a role in your immune system, people can live normal lives without it. Doctors sometimes remove the spleen after an injury or to treat certain diseases. Without a spleen, your liver and lymph nodes take over many of its duties. People who have their spleen removed need to be more careful about infections and may need extra vaccinations, but they can still enjoy full, active lives.
