3: Carbohydrate digestion begins in the mouth and is most extensive in the small intestine. The resultant monosaccharides are absorbed into the bloodstream and transported to the liver.

When food is physically changed, mechanical digestion occurs. ... Food is chemically changed in digestion when new, smaller substances are formed. These chemical changes are examples of chemical digestion. Chemical digestion begins in the mouth when enzymes in saliva begin to break down carbohydrates.

The digestive system has a lot of physical and chemical changes happening inside of it. Physical changes like grinding, crushing, and chewing and just a few examples. Chemical changes make up the majority of the changes in the system.

Review Answers. The digestive system consists of organs that break down food, absorb its nutrients, and expel any remaining food waste. The three main functions of the digestive system are digestion, absorption, and elimination. Digestion is the process of breaking down food into components that the body can absorb.

There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food. The mechanical breakdown of food occurs via muscular contractions called peristalsis and segmentation.

In physical digestion, your body mechanically breaks down food, grinding or smashing it into smaller pieces. However, during chemical digestion, enzymes, or tiny proteins, alter the structure of the food, which is made up of lots of atoms linked together.

The end products of digestion process can be listed as follows: Carbohydrates like starch and disaccharides will be digested into monosaccharides like glucose, fructose and galactose. Proteins will be digested into amino acids. Fats will be digested into fatty acids and glycerol.

Mechanical digestion involves physical movement to make foods smaller. Chemical digestion uses enzymes to break down food.

Digestive enzyme supplements Examples of digestive enzymes include: amylase — breaks apart complex sugars into smaller molecules like maltose. lipase — breaks down complex fats into smaller fatty acids and glycerol. pepsin — breaks down proteins in foods like meat, eggs, and dairy products into smaller peptides.

Mechanical digestion of food in which the food gets broken down into smaller chunks, increases the surface area for the action of enzymes and thus facilitate the chemical digestion which involves breaking down the food into simpler nutrients(so that they can be absorbed) by help of enzymes.

Chemical digestion. Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.

In the stomach, food undergoes chemical and mechanical digestion. Here, peristaltic contractions (mechanical digestion) churn the bolus, which mixes with strong digestive juices that the stomach lining cells secrete (chemical digestion).
