Briefly explain why the shape of the kidney is bean like
The kidneys are two bean-shaped organs in the renal system. They help the body pass waste as urine. They also help filter blood before sending it back to the heart.
The kidney is a bean-shaped structure with a convex and a concave border to create an area for the renal hilum, where the renal artery enters the kidney and the renal vein and ureter leave.
