The pancreas has a rich blood supply, with vessels originating as branches of both the coeliac artery and superior mesenteric artery. Structure. Venous blood is drained via veins of the same name which empty into the inferior mesenteric vein drains. (Similarly, the superior mesenteric artery and inferior mesenteric artery It can can also arise as the 2nd or 3rd branch from the inferior gluteal artery. It typically arises from a left posterior intercostal artery at the level of the 9th to 12th intercostal artery, which branches from the aorta, and supplies the lower two-thirds of the spinal cord via the anterior spinal artery. The left subclavian artery and the right subclavian artery, one on each side of the body form the internal thoracic artery, the vertebral artery, the thyrocervical trunk, and the costocervical trunk. Stylomastoid branch (from posterior auricular artery). In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas The celiac ganglia and plexus surround the vessel at its origin..

Mesenteric arterial anatomy. The human leg, in the general word sense, is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or gluteal region. The parasympathetic nerves are autonomic or visceral branches of the peripheral nervous system (PNS). The bony labyrinth and membranous labyrinth have different arterial supplies. The lesser curvature of the human stomach is supplied by the right gastric artery inferiorly and the left gastric artery superiorly, which also supplies the cardiac region. Legs are used for standing, Increased blood pressure in the portal vein, called portal hypertension, is a major complication of liver disease, most commonly cirrhosis. Inferior turbinates - note size and appearance of posterior ends. The aorta (/ e r t / ay-OR-t) is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries).The aorta distributes oxygenated blood to all parts of the body through the systemic circulation. The bony labyrinth and membranous labyrinth have different arterial supplies. The deep artery of clitoris is a branch of the internal pudendal artery and supplies the clitoral crura.Another branch of the internal pudendal artery is the dorsal artery of clitoris..
