A closer look

Spleens quietly filter your entire blood supply and diligently recycle old, worn-out red blood cells like a morbid little biological scrapyard operating in your abdomen. This squishy purple organ holds a reserve cache of blood that it forcefully ejects into your circulatory system during sudden moments of extreme physical trauma. Despite performing all these noble and heroic anatomical duties, doctors will happily surgically remove it the moment it gets slightly damaged. You can easily survive without one, proving your body has a surprisingly ruthless HR department!
