Answer 1

Answer:

Digestion is the process by which forms food is broken into simplera.

Digestion is the mechanical and chemical break down of food into small organic fragments. Mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes.

b. mixes with the food in the mouth carries the food from the mouth to the stomach.

The esophagus transfers food from the mouth to the stomach through peristaltic movements. The esophagus is a tubular organ that connects the mouth to the stomach. The chewed and softened food passes through the esophagus after being swallowed.

C. intestine.

(in vertebrates) the lower part of the alimentary canal from the end of the stomach to the anus.

d. get digested mainly in the stomach.

Protein digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.

e. The process of digestion gets completed.

Digestion involves the mixing of food, its movement through the digestive tract, and the chemical breakdown of the large molecules of food into smaller molecules. Digestion begins in the mouth, when we chew and swallow, and is completed in the small intestine.

f. In the small intestine, the digested food is absorbed by the

The middle part of your small intestine is the jejunum. The jejunum absorbs most of your nutrients: carbohydrates, fats, minerals, proteins, and vitamins. The lowest part of your small intestine is the ileum. This is where the final parts of digestive absorption take place.

g. The faeces or undigested food is passed out through the

Undigested food enters the colon where water is reabsorbed into the body and excess waste is eliminated from the anus.
