does the small intestine make enzymes?
18366
Enzymes are produced naturally in the body. For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine.

The principal function of the small intestine is to break down food, absorb nutrients needed for the body, and get rid of the unnecessary components.

The main functions of the small intestine are secretion and absorption. The epithelial cells of the small intestine secrete enzymes which digest chyme into the smallest particles, making them available for absorption.

Answer and Explanation: Most digestive enzymes are produced in the pancreas and small intestine.

Lipids (fats and oils) Digestion of fat in the small intestine is helped by bile, made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on. Bile is not an enzyme.

Digestive enzymes take the place of natural enzymes, helping to break down carbohydrates, fats, and proteins. Once foods are broken down, nutrients are absorbed into your body through the wall of the small intestine and distributed through the bloodstream.

The chyme then goes from the stomach into the first part of the small intestine, called the duodenum. This causes the pancreas to release pancreatic amylase. This enzyme breaks down the chyme into dextrin and maltose. From there, the wall of the small intestine begins to make lactase, sucrase, and maltase.

Nucleic acids (DNA and RNA) in foods are digested in the small intestine with the help of both pancreatic enzymes and enzymes produced by the small intestine itself. Pancreatic enzymes called ribonuclease and deoxyribonuclease break down RNA and DNA, respectively, into smaller nucleic acids.

In the duodenum, other enzymes— trypsin, elastase, and chymotrypsin—act on the peptides reducing them to smaller peptides. Trypsin elastase, carboxypeptidase, and chymotrypsin are produced by the pancreas and released into the duodenum where they act on the chyme.

The jejunum is one of three sections that make up the small intestine. The small intestine is part of the digestive system and is vital for breaking down and absorbing nutrients. It extends from the pyloric sphincter of the stomach to the ileocecal valve that connects the small intestine to the large intestine.

Unlike the small intestine, the large intestine produces no digestive enzymes. Chemical digestion is completed in the small intestine before the chyme reaches the large intestine. Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces.

Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.

The small intestine uses villi to adhere to the food particles entering from the stomach, while the stomach has no need for such adhesion. The villi allow multiple areas where digestive enzymes can be released by the small intestine.

Trypsin function. Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach. It may also be referred to as a proteolytic enzyme, or proteinase.

The small intestine uses bile to emulsify and break down large fat globules into smaller pieces, which allows the lipase enzymes to break down the lipids into fatty acids.

Chemical digestion in the small intestine relies on the activities of three accessory digestive organs: the liver, pancreas, and gallbladder (Figure 1).

Answer: The small intestines are well adapted for absorbing nutrients during digestion by: being very long, having villi and micro villi that increase surface area, using muscular contractions to move and mix food, and receiving and housing digestive enzymes and bile that help the breakdown of food.
