Renal hilum
Renal Hilum
The Renal Hilum (/rɪˈnæl ˈhaɪləm/), also known as the Hilum of Kidney, is a crucial part of the kidney that serves as the entrance for the renal artery and renal vein, and the exit for the ureter.
Etymology
The term "Renal Hilum" is derived from the Latin word "Renalis" meaning "of the kidneys" and the Greek word "Hilum" meaning "small thing", indicating its small but significant role in kidney function.
Anatomy
The Renal Hilum is located on the medial side of each kidney, and it is the point where the renal artery enters, the renal vein exits, and the ureter leaves the kidney. This area is also where the nerves and lymphatic vessels are located. The structures within the hilum are, from anterior to posterior, the renal vein, renal artery, and renal pelvis. This arrangement allows for the efficient transport of blood and urine to and from the kidney.
