The spleen is often referred to as the body's "blood bank".
Why is the Spleen Called the Blood Bank?
The spleen plays a crucial role in blood purification and storage. It filters blood, removing old or damaged red blood cells (RBCs) and microbes. Importantly, the spleen also stores a reserve of blood cells, which can be released into circulation during emergencies such as hemorrhagic shock (significant blood loss). This storage capacity contributes to its nickname as the "blood bank." Additionally, it's sometimes called the "graveyard of red blood cells" due to its role in removing worn-out RBCs from the bloodstream.
