Vitamins that are water- soluble directly enter the bloodstream. Examples of these vitamins are B vitamins, biotin, pantothenic acid, folate and vitamin C.
All of them.
Digestion and absorption by osmosis
Alcohol and poison
Nutrients leave the gut and enter the bloodstream through the lining of the small intestine.
to the bloodstream
Because medication enters directly into the bloodstream through an IV but pills must dissolve before they can enter the bloodstream
your body absorbs the nutrients in food through the lining of your stomach and intestine, and they go directly into the bloodstream. Alcohol does this too, that is why the cops measure your BAC, Blood Alcohol Content.
Nutrients travel from your intestines to your liver in a few simple steps. When nutrients enter your small intestine, the small villi filter out the vital nutrients needed for bodily functions. Then, these nutrients are separated from the other contents - which move on to the large intestine for further filtering - and the nutrients are sent to the capillaries. The capillaries then send the nutrients throughout the blood. The red blood cells then transport the nutrients throughout the body's organs, including the liver!
through cells
absorption
The small intestine. It has villi that absorb nutrients and then transport them to the bloodstream.
Villi on the wall of the small intestine absorb nutrients into the bloodstream.
