primarily retroperitoneal
Are the lower parts of the ureters and urinary bladder, and urethra primarily retroperitoneal, subperitoneal, or mesenteric?
subperitoneal
Is the kidney primarily retroperitoneal or subperitoneal?
primarily retroperitoneal
Kidney contains 2 systems:
Vasculature (blood filtration) and collection ducts (waste excret)
What attaches the kidney in place?
the ureter and vessels (other than that it floats in fat)
Name the superior, inferior, lateral, and medial borders of the kidney
Suprarenal Gland, iliac creat, ….., reneal hilum (M)
What is the Renal Hilum and what is inside it Anterior to Posterior?
Conduit Space for vein, art, renal pelvis as becomes ureter
What does the Left kidney span? What rib is it protected by?
T11-L2 (protected by ribs 11 and 12)
What does the right kidney span? What rib is it protected by?
T12-L3 (protected by rib 12)

Perinephric Space, renal fascia, and perinephric fat (found in paravertebral gutter)
External to the renal fascia is ___ within the paranephric space
paranephric/pararenal fat
Excretory (collection pathway)
Collecting ducts –> minor calices –> major calices –> renal pelvis –> ureter
Kidney supplied by _____ arteries that arise from ____ between L1 and L2 vertebrae
