to a molecular level
Molecules that can pass through the wall of the small intestines are products that are broken down from starch, lipids and protiens.Starch breaks down into maltose which is then further broken down into glucose, which is absorbed by the intestine.Lipids break down into glycerol and fatty acids, which are absorbed by the intestines.Protiens break down into amino acids, which are absorbed by the intestines.Vitamins are minerals are alos absorbed by the intestines.Water is also absrobed by the small intestines, but is also absrobed by the large intestines.
They are broken down and absorbed into the blood.

AnswerSince most all nutrients that a human needs are absorbed via the digestive system. All carbohydrates, proteins, and fats are absorbed in the small intestine.AnswerThings are absorbed throughout the entire system, with the exception of the esophagus. Some glucose, for example, can be absorbed in the mouth. Water, alcohol, and some nutrients are absorbed in the stomach. Most nutrient absorption occurs in the small intestine. Water and some minerals and vitamins are absorbed in the colon. Most vitamin K is produced by bacteria in the colon and absorbed there.
The small intestine and is involved in the process of digestion. nutrients such as carbohydrates, protein, fats, and many vitamins and minerals are absorbed by your small intestine. the small intestine stretches from your stomach to the beginning of your large intestine. it is broken in to three distinct zones - the duodenum, the jejunum, and the ilium
small intestine
The nutrients that do not need to be digested they have to be smaller than the cells of the small intestine. Some of these are sugars and amino acids.
So that it can be small enough to pass through a cell's membrane.
The stomach breaks down food mechanically and also produces chemicals for digestion. Most of the nutrients broken down in digestion are absorbed by the small intestine In the large intestine, water and minerals are absorbed and waste material is stored. Solid waste is eliminated through the rectum.
Food is broken down or digested in the stomach but the nutrients are not absorbed in the stomach. Nutrients from digested food are primarily absorbed in the small intestine.
Anything not absorbed by the small intestine will eventually exit through the rectum.
