Do we have the same blood that we have always had since birth? Does it constantly recycle? If it dies, where does it go?
In: Biology
Your body is constantly making new blood and recycling blood cells that die. Each blood cell lives an average of 21 days, and when it is fragile, the spleen breaks it down and absorbs whatever it can salvage from inside the cell so your body can make new ones. This is why donating blood is safe – your body will realize it’s missing some and produce more than usual to get back to where it wants to be
