Microanatomy of Kidney

Admin

Main Model


Zone A : Renal sinus

At the concave medial margin of each kidney is a vertical cleft, the renal hilum, which is the entrance to a space within the kidney, the renal sinus. Structures that serve the kidneys (vessels, nerves and structures that drain urine from the kidney) enter and exit the renal sinus through the renal hilum.
