What does the blood carry from the intestines?
the nutrients of the digested food.
The hepatic (portal) system refers to the blood vessels that carry blood from the intestines, stomach, pancreas and spleen to the liver. Blood containing nutrients or drugs absorbed from the intestine is transported by the hepatic portal system to the liver for metabolism before distribution to the rest of the body.
The intestines absorb all of the molecules that are from the broken down/part digested food. The intestines have a massive blood flow through them, so all of these molecules are diffused through the villi (the inside wall of the intestines) and into the bloodstream. In short, the intestines are what actually gets the nutrients into our blood.
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…
Arteries always carry blood away from the heart. Veins always carry blood back to the heart. In almost all cases, arteries carry oxygenated blood. And veins carry deoxygenated blood. The exception to this rule is that pulmonary veins carry oxygenated blood from the lungs to the heart and Pulmonary arteries carry deoxygeneted blood.
No. The stomach churns the food up. The food then mixes with chyme (KYME) and it goes down into the intestines the intestines absorb the cell-sized food into the blood.
