Describe the route of nutrients after digestion

Question

From intestinal lumen via to the tissues - describe the route of nutrients after digestion?

Answer 1

Amino acids, Monosaccharides, mineral salts and water are absorbed by intestinal epithelium and collected by the capillary vessels of intestinal villi. From capillaries, nutrients go to the mesenteric circulation, a system of vessels which drains the intestinal loops. The blood of the mesenteric circulation is drained to the portal hepatic vein and certain nutrients are processed by the liver. From liver, nutrients are gathered by the hepatic veins which release its blood content into the inferior vena cava. The blood from inferior vena cava then profits the right chambers of the heart and is pumped to lungs for oxygenation. From lungs, the blood then returns to the heart where it is pumped to the tissues distributing oxygen and nutrients.
