The procces is called absorption. If you want to get technical, however, the name of the process depends on what the nutirent being absorbed is. For instance sodium is absorbed using a protein carrier, glucose uses that same carrier but for glucose it is called a symporter because it takes a "free" ride with sodium. Once the nutirents cross the intestinal wall they are sent to the mesenteric veins which take them to the liver and then to the circulation. If the absorbed nutrient is a big fat molecule then it takes a different path; it is picked up the the lacteals and sent directly to the circulation, thus bypassing the liver.
Villi on the wall of the small intestine absorb nutrients into the bloodstream.
some of the radiation is absorbed in the atmosphere
Simple sugars can be absorbed directly into the bloodstream to provide energy for cell use quickly.
when we eat food it is finally converted into the most basic form i.e. glucose so when we drink glucose directly it is directly absorbed by the cells without processing in the stomach so it gives instant energy
Active transport driven directly or indirectly by metabolic energy ;)
Water-soluble glycerol and short and medium chain fatty acids.
Its not digested as it is easily small enough to be absorbed directly. It Moves through channels called aquaporins that are present on the intestinal villus cells following the osmotic gradient set by sodium.
Fats are absorbed in the small intestine, along with carbohydrates and proteins.
Many arterioles that penetrate the Submucosa give rise to capillary networks that supply the Intestinal Glands and villi with blood.
no
corporate and business unit level of strategy
Long chain fatty acids
Alcohol is a liquid that is absorbed directly into the blood stream from the stomach. Food is absorbed through the intestines, but it must be broken down first. That is why alcohol is absorbed faster.
The precursor molecule is incorporated directly into the final penicillin molecule.
