Left side of upper thoracic wall and thoracic viscera. VEINS DESCRIPTION AND TRIBUTARIES REGIONS DRAINED Inferior vena cava (See Figure 21.24 .) Inferior phrenic veins (FREN-ik = pertaining to diaphragm) Arise on inferior surface of diaphragm. Left inferior phrenic vein usually sends one tributary to left suprarenal vein, which empties into left renal vein, and another tributary into inferior vena cava. Right inferior phrenic vein empties into inferior vena cava. Inferior surface of diaphragm and adjoining peritoneal tissues. Hepatic veins (he-PAT-ik = pertaining to liver) Typically two or three in number. Drain sinusoidal capillaries of liver. Capillaries of liver receive venous blood from capillaries of gastrointestinal organs via hepatic portal vein. Hepatic portal vein receives the following tributaries from gastrointestinal organs: 1.Left gastric vein arises from left side of lesser curvature of stomach and joins left side of hepatic portal vein in lesser omentum. 2.Right gastric vein arises from right aspect of lesser curvature of stomach and joins hepatic portal vein on its anterior surface within lesser omentum. 3.Splenic vein arises in spleen and Terminal esophagus, stomach, liver, gallbladder, spleen, pancreas, small intestine, and large intestine. Lesser curvature of stomach, abdominal portion of esophagus,
VEINS DESCRIPTION AND TRIBUTARIES REGIONS DRAINED crosses abdomen transversely posterior to stomach to anastomose with superior mesenteric vein to form hepatic portal vein. It receives near its junction with hepatic portal vein, it receives inferior mesenteric vein , which receives tributaries from second half of large intestine. 4.Superior mesenteric vein arises from numerous tributaries from most of small intestine and first half of large intestine and ascends to join splenic vein to form hepatic portal vein. stomach, and duodenum. Spleen, fundus and greater curvature of stomach, pancreas, greater omentum, descending colon, sigmoid colon, and rectum. Duodenum, jejunum, ileum, cecum, appendix, ascending colon, and transverse colon. Lumbar veins (LUM-bar = pertaining to loin) Usually four on each side; course horizontally through posterior abdominal wall with lumbar arteries. Connect at right angles with right and left ascending lumbar veins , which form origin of corresponding azygos or hemiazygos vein. Join ascending lumbar veins and then connect from ascending lumbar veins to inferior vena cava. Posterior and lateral abdominal muscle wall, lumbar vertebrae, spinal cord and spinal nerves (cauda equina) within vertebral canal, and meninges. Suprarenal veins (soo′-pra- RĒ-nal; supra - = above) Pass medially from adrenal (suprarenal) glands (left suprarenal vein joins left renal vein, and right suprarenal vein joins inferior vena cava).
