The adrenal (or suprarenal) glands are paired endocrine glands situated over the medial aspect of the upper poles of each kidney. In the kidney, the blood drainage starts with the peritubular plexuses that give off fine venules that form the interlobular veins. While the upper LSRV is a tributary of IVC, the lower LSRV is a tributary of the left renal vein. Suprarenal veins. Human cardiovascular system - Human cardiovascular system - Inferior vena cava and its tributaries: The inferior vena cava is a large, valveless, venous trunk that receives blood from the legs, the back, and the walls and contents of the abdomen and pelvis.
