How does mechanical digestion enhance chemical digestion?
Solution
The digestion is defined as the breakdown of large food molecules into small water-soluble smaller molecules. These simpler forms of food molecules are then absorbed. In some organisms, these smaller substances are then absorbed by the small intestine in the bloodstream.
Complete answer:
The meal is divided into smaller parts through mechanical digestion, so that digestive enzymes have a wider surface area. Without the assistance of additives, mechanical digestion is the dissolution of fruit. The action of chemicals in the body to divide big food molecules into smaller ones is chemical digestion.
Mouth-
Chewing food splits it into tiny parts so that it can be taken to the stomach by the esophagus. Chewing also combines the fragments of food with saliva, which contains starch breakdown enzymes.
Stomach-
The bolus moves to the stomach, where peristalsis (a contraction of the stomach walls) physically churns the food and is combined with stomach acid and further digestive enzymes.
Small intestine
The food is processed through the digestive system through smooth muscle contractions called segmentation. The food is isolated by segmentation and then placed back together, combined with digestive juices and pushed against the mucosa to be swallowed. Another form of peristalsis pushes the remaining farther down the small intestine to the big intestine for subsequent evacuation after most of the food has been consumed.
Note: The bolus moves to the stomach, where peristalsis (a contraction of the stomach walls) physically churns the food and is combined with stomach acid and further digestive enzymes. Humans are unable to digest cellulose and there is a lack of the necessary enzymes to break down the linkages of beta acetal. The fiber that assists in the smooth functioning of the intestinal tract is indigestible cellulose. Cellulose cannot be digested immediately by any vertebrate.
