The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine.
If you drink large amounts, your liver starts to have a hard time processing the alcohol. If your liver cells are worked too hard, they can start to become damaged. This damage can lead to fatty liver or fibrosis (scarring of the liver) and sometimes cirrhosis (serious liver damage).
