Most of us take for granted our kidneys.  Unless we’ve been told otherwise, we assume we have two functioning kidneys about the size of a fist doing their day-to-day job of keeping the composition of our blood stable allowing the body to function.  These bean-shaped organs work hard at preventing buildup of wastes and extra fluid in the body along with stabilizing electrolytes of sodium, potassium, and phosphate among other duties they do. As long as they are performing as they should, we barely think about the fact of “what if I only had one kidney?”
