- little bit of fat and skin
What is pararenal fat?
Fat directly touching the kidneys
What is perirenal fat?
Fat that is not directly touching the kindey’s but is surrounding them

Posteriorly
Where does the right renal artery run compared to the IVC?
Posteriorly
How much of the cardiac output passes through the renal arteries to be filtered?
1/3
What is a tributary to the IVC?
Renal veins
Where does the left renal vein pass compared to the SMA and the aorta? (2)
- Posterior to the SMA
2. Anterior to the aorta
What do the renal veins do?
Drain the kidneys of blood and carries blood purified by the kidneys

Where do ureters originate?
In the renal pelvis
Where do ureters lay?
