What is a Kidney ?
The Kidneys are pear shaped digestive organs located in the upper abdomen which play a key role in bodily functions. Their main functions are blood filtering and getting rid of bodily waste thereby balancing the electrolyte levels in the body. The kidneys are also vital for controlling blood pressure and stimulating the production of red blood cells. The kidneys are located in the abdomen, one on each side of the spine. Kidneys get their blood supply through the renal arteries directly from the aorta and send blood back to the heart via the renal veins to the vena cava.
