Venous drainage:- Follows the same pattern as the arteries.- The right renal vein enters the inferior vena cava.- The left renal vein receivesa The left gonadal vein,b The left suprarenal vein, andc The left Inferior phrenic vein, and may receive A root of the hemiazygos vein before crossing anterior to the aorta to join the IVC.
