Study Notes
Kidney Anatomy and Function
- The hilum of the kidney is situated on the medial surface where renal blood vessels, nerves, and the ureter enter and exit the kidney.
- The ureter functions as a muscular tube that transports urine from the kidneys to the bladder through peristaltic movements.
- The renal artery arises directly from the abdominal aorta, supplying oxygenated blood to the kidneys for filtration.
- A kidney is composed of three main parts: the cortex, medulla, and renal pelvis, each playing distinct roles in kidney function.
- Ureteric constrictions are found at three specific points:
- At the junction of the renal pelvis and ureter
- Where the ureter crosses the pelvic brim
- At the entrance to the bladder, where the ureter opens into the bladder wall.
