Question

What is the function of the hepatic portal systems and which organs are involved with it?

Answer 1

Hepatic portal vessels in humans

1.Superior mesenteric vein - drains small intestine, ascending & transverse colon & greater curvature of stomach (right gastroepiploic vein)

2.Inferior mesenteric vein - drains descending & sigmoid colon, merges with pancreatic vein & splenic vein, then merges with superior mesenteric vein

3.Right & left gastric veins - drains lesser curvature of stomach

4.Cystic vein - drains gall bladder

Hepatic portal vein - above 4 veins merge to form HPV which enters liver, carries deoxygenated blood and digested food into liver sinusoids for processing. Some nutrients such as glucose, fatty acids & amino acids are removed in the liver or modified for cell use. Some harmful substances are detoxed in liver

Hepatic arteries carry oxygenated blood to liver

Hepatic veins carry blood from liver to inferior vena cava
