Well, the large intestine extracts large amounts of nutrients but cannot get the liquid nutrients out. So, getting the liquid nutrients out is the small intestines job. BTW You can get this answer on wikapedia
In small intestine pep-tides are broken down to amine acids by pancreatic enzymes trypsin andchymotrypsin. Pancreatic amylase brake down the carbohydrates to bisaccharide level. Pancreatic lipase brakes down Fats to Fatty acids and glycerol with the help of bile salts. In the last enzymes present in intestinal cells brake down the bisaccharide tomonosaccharides during absorption.
No digestion occurs in the gallbladder, but the gall bladder can produce a greenish liquid called gall/bile, and that gall/bile flows into your small intestine to help digest food there. To be more specific, bile salts aid in the digestion of fats in the small intestine.
1. The small intestine is LONG- this ensures food remains in the small intestine long enough for the products of digestion to be fully absorbed into the bloodstrem. 2. The Small intestine is HIGHLY FOLDED into villi (s. villus)- This gives a greater surface area for more efficient diffusion of products into the bloodstream. 3. The small intestine has a RICH BLOOD SUPPLY - Each villus has a network of capillaries so that the products of digestion are carried away from the small intestine efficiently. 4. The epithelium of the small intestine in the villi is only ONE CELL THICK - for easier diffusion of the products of digestion into the bloodstream. The walls of the capillaries are only one cell thick as well!!
Colon cancer is a type of cancer that occurs in the large intestine (colon), which is the final part of the digestive tract12. The large intestine is about 5 feet long and absorbs water and salt from the food that passes through it. The small intestine, also called the small bowel, is a long tube that connects the stomach and the large intestine. It is about 20 feet long and is responsible for digesting and absorbing nutrients from the food that enters it. Cancer of the small intestine is much less common than cancer of the large intestine. There are different types of small bowel cancer, such as adenocarcinoma, neuroendocrine tumors, lymphoma, and sarcoma. Therefore, colon cancer occurs most often in the large intestine, not the small intestine.
The duodenum is where breakdown begins in the small intestine and the jejunum is where nutrient absorption "completes." The small intestine receives secretions from the liver and the pancreas. The half-digedted food from the stomach is acidic due to the hydrochloric acid produced by the stomach. In the small intestine, bile from the liver makes it alkaline (basic) so that the pancreatic juices can act on the food. Bile also acts on fats, which exist as fat globules, and breaks them into smaller globules. This is called emulsification of fats. The pancreas releases trypsin, lipase and some other enzymes into the small intestine. Trypsin acts on proteins and lipase acts on emulsified fats. Finally, some intestinal juices secreted by the small intestine itself convert the proteins into amino acids, carbohydrates into glucose and fats into fatty acids and glycerol. All these are absorbed by tiny finger-like projections in the small intestine, called the villi, which are well supplied with blood vessels.
Proteins are digested in your stomach. Pepsinogen is secreted by the chief cells. Pepsinogen is converted to pepsin by hydrochloric acid. This pepsin brakes the peptide bond of proteins to form polypeptides.

The small intestine is a water recovery system. Earlier stages of digestion use a lot of water, and then the water is reabsorbed in the small intestine.
small intestine
Yes. This occurs initially in the stomach and small intestine. After digestion, further metabolism takes place in the liver, for example.
Mechanical digestion.
By definition mechanical digestion is a physical part of digestion.
Mechanical
movement of chyme from the stomach to the small intestine is regulated by what
The type of digestion that chewing is referred to as is mechanical digestion.
