The kidneys act as filters to clean the blood. They get rid of waste and send along filtered fluid. The tiny filters in the kidneys are called glomeruli.
When kidneys are healthy, the artery brings blood and waste from the blood to the kidneys. The glomeruli clean the blood. Then, waste and excess fluid out in the urine through the ureter. The clean blood leaves the kidneys and re-enters the bloodstream through the vein.
