The soluble portions of food are absorbed by the small intestine into the bloodstream.
Energy. All food eaten is digested. Food is a chemical that, once digested, turns to energy :) Thats what I Learnt Anyway :)
Yes. Your stomach is what digests food. Once the food is digested, the nutrients are taken by your bloodstream to the rest of your body.
Once the food is chewed and is swallowed it is referred to as a bolus. Once it enters the stomach and is churned and exposed to the gastric secretions it enters the duodenum becoming chyme.
To rid the body of the waste material once the nutrients of the food eaten have been extracted and digested.
The digestive tract has many processes in digesting food, some of which begin in the mouth. Once food has entered the mouth, an enzyme in your saliva along with your teeth, help in initially breaking the food down. Once it is broken down to a point at which it can be swallowed, it enters the stomach. Powerful acids inside the stomach break the food down much more. Once it has been digested in the stomach, it passes through to the small intestine, which is very long. The digested food will travel the small intestine until it reaches the large intestine, or colon. All along on the journey, nutrients have been "sucked" out of the food and deposited into the body. However once entering the large intestine, moisture is what will now be "sucked" out of the digested matter. That is why you can get constipated if the matter is in your large intestine too long, or you can have diarrhea if it passes through too quickly. Once the digested matter has reached the end of the large intestine, or colon, it is ready to be ejected as waste matter. Thus, causing David to take a dump. By taking the dump, his body was getting rid of the waste matter it could not use. I hope that helps explain what you wanted to know and answer any questions you had. If you have any additional questions which I did not answer, or perhaps you would like to learn more about what happens inside the intestines, as I just went over it briefly, I would suggest google-ing "The Digestive Process", or something to that degree.
Animals digest their food through a series of processes that break down the nutrients into smaller, absorbable molecules. These nutrients are then absorbed into the bloodstream and used for energy, growth, and repair of body tissues. Waste products that cannot be digested are eliminated from the body as feces.
In the small intestine most food is digested. The digestive system's organs work to make the food you eat soluble, so your body can absorb the energy (glucose). Once the churned up food is in the small intestine which is covered in villus (like a brush) the microvilli on the villus, to increase the surface area further, absorb all of the soluble glucose. Inside of the villus are capillaries that absorb most of the churned up food. But fatty acids called LIPID cannot be absorbed, so the lacteal running though the middle of the villus absorbs the fatty acids.:) hope that helped?
In the small intestine is where the breakdown of large food molecules occur and it also absorbs all of all the nutrients from these large molecules.
All the proteins in the food is consumed. Once it enters the body it has to be digested to amino acids and not the proteins in the food directly go and attach in human cells.
it is in mouth that the food we eat is broken in to small pieces which makes it easier to be digested (large molecules of food converted to small once)
Once food has been properly digested in the stomach and further in the small intestine, the nutrients are absorbed by the small intestinal wall and its internal folds called villi. This villi look similar to a human finger and inside have capillary blood vessels and lacteals. The former carry away sugars and proteins to be distributed throughout the body using the circulatory system while the latter distribute fats through the body using the lymph system.Through the Endocrine system, and it's glands.
