What is a primary function of the spleen in the human body?

Explanation

The spleen is an organ located in the upper left abdomen that filters blood, removing old or damaged red blood cells and helping the body fight certain infections as part of the immune system. It also acts as a reservoir, storing platelets and white blood cells that can be released into circulation when needed. While the spleen performs valuable functions, a person can survive without it, since other organs like the liver can take over some of its blood-filtering roles.
