Superior Mesenteric Artery Common Lliac Artery

In human anatomy, the superior mesenteric artery (SMA) arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.

Ulnar Artery

The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspect of the forearm. It arises from the brachial artery and terminates in the superficial palmar arch, which joins with the superficial branch of the radial artery. It is palpable on the anterior and medial aspect of the wrist.

Along its course, it is accompanied by a similarly named vein or veins, the ulnar vein or ulnar veins.

The ulnar artery, the larger of the two terminal branches of the brachial, begins a little below the bend of the elbow in the cubital fossa, and, passing obliquely downward, reaches the ulnar side of the forearm at a point about midway between the elbow and the wrist. It then runs along the ulnar border to the wrist, crosses the transverse carpal ligament on the radial side of the pisiform bone, and immediately beyond this bone divides into two branches, which enter into the formation of the superficial and deep volar arches.

Radial Artery

In human anatomy, the radial artery is the main blood vessel, with oxygenated blood, of the lateral aspect of the forearm.

Portal Vein

The hepatic portal vein (often simply portal vein) is a vein in the abdominal cavity that drains blood from the gastrointestinal tract and spleen. It is usually formed by the confluence of the superior mesenteric and splenic veins, and also receives blood from the inferior mesenteric, gastric, and cystic veins. The hepatic portal vein is a major component of the hepatic portal system, one of the main portal venous systems in the body.

Hepatic Vein

In human anatomy, the hepatic veins are the blood vessels that drain de-oxygenated blood from the liver and blood cleaned by the liver (from the stomach, pancreas, small intestine and colon) into the inferior vena cava.
