“The deeper you go, the sweeter it gets.”
Adrenal Circulation
- Both the left and right adrenals receive arterial blood supply in the same fashion
- paired superior suprarenal arteries – derived from inferior phrenic arteries
- paired middle suprarenal arteries – derived directly from abdominal aorta
- paired inferior suprarenal arteris – derived from the adjacent renal arteries
- The left and right adrenals have differing venous drainage
- left adrenal venous drainage is through the left adrenal vein to the left renal vein and finally to the IVC
- right adrenal venous drainage is through the right adrenal vein to the IVC
- Recall the same pattern for the left and right gonadal artery/vein
