Blood should never be flowing "in" the intestines--that is a serious problem. Instead, blood passes thru the arteries of the intestines into capillaries then thru venules into veins and ultimately into the portal vein to the liver.

Food passing through the intestines after ingesting gets broken down by the acids into basic amino acids, fats and minerals, like iron. It goes from lumen into microvilli to villi to venules to veins into the portal vein to the liver. Fats are directly absorbed into lacteals into the portal vein and then liver. The blood vessels feeding the small intestines adds fluids to the intestinal content. In the large intestines, the excess fluid is pulled back out and transported to the kidneys with the aid of blood flow.

The functions of the small intestine are to collect nutrients,minerals, and moisture from the food that you eat to get energy for your body.
