What is the function of pyramid in a kidney?

The renal pyramid, found in the medulla of the kidney, plays a crucial role in urine formation. It contains structures called nephrons, which are responsible for filtering blood, reabsorbing essential substances, and excreting waste as urine. The pyramids also help transport urine from the nephrons to the minor calyces, ultimately leading to the renal pelvis and bladder. Their conical shape facilitates efficient drainage of urine into the collecting system.
