Inferior vena cava Formed by union of left and right common iliac veins anterior,just to the right of L4~L5 Ascends on the right side of aorta,pierces caval opening of diaphragm at the level of T8. and drains into the right atrium Conveys blood from the whole body below the diaphragm to the right atrium
Inferior vena cava ❑ Formed by union of left and right common iliac veins anterior , just to the right of L4~L5 ❑ Ascends on the right side of aorta, pierces caval opening of diaphragm at the level of T8, and drains into the right atrium ❑ Conveys blood from the whole body below the diaphragm to the right atrium
Inferior vena cava Chief tributaries ▣Parietal >Paired inferior phrenic v. >paired lumbar v.(4) ▣Visceral >Right and left renal veins Right suprarenal vein (left drain into left renal vein) >Right testicular or ovarian v. (left drain into left renal vein) >Hepatic veins:right,left and intermediate
Inferior vena cava Chief tributaries ❑ Parietal ➢ Paired inferior phrenic v. ➢ paired lumbar v. (4) ❑ Visceral ➢ Right and left renal veins ➢ Right suprarenal vein (left drain into left renal vein) ➢ Right testicular or ovarian v. (left drain into left renal vein) ➢ Hepatic veins : right, left and intermediate
Hepatic portal vein General features Formed behind the neck of pancreas by the union of superior mesenteric and splenic veins Ascends upwards and to the right,posterior to the first part of duodenum and then enters the lesser omentum to the porta hepatis,where it divides into right and left branches ▣no functional valves Drains blood from Gl tract from the lower end of esophagus to the upper end of anal canal,pancreas,gall bladder,bile ducts and spleen
