The aorta begins at the left ventricle of the heart, and nearly all the blood pumped by the heart passes through it. The aorta is about as thick as a garden hose. The aorta loops over the heart before moving downward through the trunk of the body, in a "candy cane" shape. Many other arteries branch off from the aorta to supply blood to all the parts of the body.

The veins that drain into the portal vein (ie above the ansastmoses between the splenic and sup. mesenteric) are the cystic vein, the right gastric vein and the posterior-superior part of the pancreaticoduodenal vein.
