not completely digested,and when digested the useful materials are absorbed mostly by the lining of small intestine.
digest food
Diffusion is how gas exchange happens in the lungs, so it is useful for respiration. Food susbstances also diffuse out of the small intestine once they have been digested, so it's useful for that as well.
You will get constipation
Once it leaves the stomach, the partially digested contents (technical term - "chyme") enter the small intestine at the duodenum. As the chyme passes through the small intestine, further digestion takes place, as well as the absorption of useful nutrients.
The small intestine is useful for the Digestion of fats, proteins and carbohydrates contained in the foods you consume, is completed within the small intestine.
The function (job) of the intestine is to digest and absorb food. Digestion means breaking down food into soluble substances which can be absorbed. For example, starch is broken down into sugar (glucose) and protein is broken down into amino acids. So, the substances which are taken in by the blood from the intestine are digested foods, for example sugar (glucose) and amino acids. Most food is absorbed by the small intestine. Undigested food and water pass into the large intestine which takes some of the water back into the blood.

Through digestion, we chew the food we eat and we swallow it. Then, it gets to the stomach where it is mixed together with water and other fluids. After that, the food is passed on to the intestine. Nutrients escape through the walls of the intestine into our blood. From there they are carried to all parts of the body. Most food leaves waste that the body cannot use. Some of it goes to the kidneys and turns into urine. The liver also filters out waste. What is left over passes through the large intestine and leaves our body.
