Each adult kidney weighs about 125-170g for males and 115-155g for females, and it is approximately 10-12cm in length, 5-6cm in width and 3-4cm in thicken. Also, the kidney has a bean-shaped structure with a convex and concave surface. Within each kidney, there are two important parts: renal parenchyma and renal pelvic.

The outer part of renal parenchyma is called renal cortex, while the inner part is called renal medulla. Renal cortex consists of more than one million of nephrons that include glomerulus, renal capsule and renal tubule. Renal medulla contains 10-20 renal pyramids. The top of renal pyramid is named renal papilla. The papilla empties urine into a minor calyx, and minor calyxes empty into major calyxes and then the renal pelvis. Renal artery is where blood enters into the kidney, while renal vein is where blood exits the kidney. The perfect structure of kidney determines the great kidney function.
