Identify the following structures in the kidney: cortex, medulla, renal pyramids, renal columns, renal pelvis, minor calyx, major calyx, interlobular arteries, arcuate arteries, interlobular veins, renal artery, renal vein.

The cortex is a yellowish-red band that is located immediately below the fibrous capsule.
The medulla is a central, dark red area that contains triangular zones called renal pyramids or Malpighian pyramids.
The renal pyramids are striated structures that seem to extend the Malpighian pyramids to the cortex but without reaching it.
The renal columns are extensions of the cortex that penetrate the medulla and separate the renal pyramids.
The renal pelvis is a funnel-shaped structure located within the renal sinus and narrows medially to form the neck of the renal pelvis, which continues as the ureter.
The minor calyx is a small duct located around each papilla that culminates in three to five major calyces.
The major calyces unite and give rise to the formation of the renal pelvis.
The interlobular arteries penetrate the interlobules and give rise to the interlobular arteries or cortical radiated arteries, from which the arterioles of the glomeruli originate.
The arcuate arteries are branches of the interlobular arteries that run parallel to the base of the renal pyramids.
The interlobular veins drain into the arcuate veins, which are located in the renal columns and drain into the renal vein.
The renal artery is a branch of the abdominal aorta and is usually divided into two branches, one for each kidney.
The renal vein is located in the renal sinus and is formed by the union of the interlobular veins and the veins of the renal pelvis.
