ANATOMY

Detailed explanation-1: -The renal hilum is also called renal pedicels. It is the central recessed area which is concave at centre and convex towards the periphery. This is the area where the renal artery enters the kidney and the renal vein and the ureters exit the kidney.

Detailed explanation-2: -Each renal artery enters a kidney at a site called the renal hilum. This area is the entry and exit point for vessels and nerves that feed into the kidneys. From there, the artery branches into smaller blood vessels throughout the kidney.

Detailed explanation-3: -The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney; it is also the point of exit for the ureters-the urine-bearing tubes that exit the kidney and empty into the urinary bladder. The renal pelvis connects the kidney to the rest of the body.

Detailed explanation-4: -Ureters, blood vessels, lymph vessels, and nerves enter and leave at the renal hilum. The renal arteries arise directly from the aorta, and the renal veins drain directly into the inferior vena cava.

Detailed explanation-5: -The medial concave border of a kidney contains a notch known as hilus through which the renal artery enters and the renal vein and ureter leave the kidney.
