An interactive, Flash animated diagram of a nephron, and the process of urine formation within it before excretion from the human body. The kidneys regulate the specific balance of chemicals within the blood the body needs to work properly—this balance affects blood pressure, volume, and pH—removing waste and excess water from the body in the form of urine, and reabsorbing necessary nutrients. Click through an animated slide show to learn step-by-step how urine is formed.
