Your kidneys play a vital role in keeping your blood composition constant. They filter your blood to remove excess water and waste products, which are secreted from your kidneys as urine. One quarter of your blood supply passes through your kidneys every minute. It enters your kidney and is distributed to minute filtration units known as nephrons.
All blood in the body flows through the kidneys every 10 minutes, so your blood is filtered for toxins 150 times a day. Structure: A kidney has 2 distinct parts: the cortex on the outside and the medulla on the inside. The medulla leads into an area called the pelvis (sometimes called the renal pelvis).
