Anatomy and Physiology: Digestive System In anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine (jejunum and ileum). At its termination behind the neck of the pancreas, the SMV combines with the splenic vein to form the hepatic portal vein.The SMV lies to the anatomical left of the similarly named artery, the superior mesenteric artery, which originates from the abdominal aorta.t its termination behind the neck of the pancreas, the SMV combines with the splenic vein to form the hepatic portal vein.

Superior mesenteric artery syndrome The superior mesenteric artery is a large artery in the abdominal cavity that provides blood to the small intestine, cecum, and colon.The small intestine is the portion of the digestive system most responsible for absorption of nutrients from food into the bloodstream.uperior mesenteric artery syndrome (SMAS) is a digestive condition that occurs when the duodenum (the first part of the small intestine) is compressed between two arteries (the aorta and the superior mesenteric artery). This compression causes partial or complete blockage of the duodenum.

Human Physiology/Print Version From Wikipedia, the free encyclopedia. The superior vena cava (also known as the cava or cva) is a large diameter (24 mm), yet short, vein that carries deoxygenated blood from the upper half of the body to the heart 's right atrium.It is located in the anterior right superior mediastinum.o valve divides the superior vena cava from the right atrium. As a result, the (right) atrial and (right) ventricular contractions are conducted up into the internal jugular vein and, through the sternocleidomastoid muscle, can be seen as the jugular venous pressure.
