Q. From the intestinal lumen through to the tissues - what is the route of nutrients after digestion?

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