Examples of mechanical digestion

Answer 1

in the Mouth the salivary glands secrete saliva and the saliva contains an enzyme called amylase amylase breaks down carbohydrates(starch) into dysacherides (two) and monosacherides they are simply sugars/glucose

in the stomach the stomach has an acid called hydrochloric acid

and it has an enzyme called pepsinogen. Hydrochloric activate pepsinogen into pepsin. Pepsinogen enzyme only works in an acidic environment and when it gets mixed with the hydrochloric acid it creates an enzyme called pepsin. Pepsin breaks down proteins into amino acid chains

Answer 2

mechanical digestionis the grinding and tearing action of the teeth, the mixing and mashing action of the tonge, the churing of the food by the muscles in the digestive track and the breaking down of the fat droplets through the action bile.

Answer 3

chewing

1. Ingestion = taking food into the mouth

2. Movement of Food = The passage of food along the GI tract

3. Digestion = the breakdown of food by chemical and mechanical means

4. Absorption = the passage of digested food from the GI tract into the bloodstream and lymph for distribution to cells

5. Defecation = elimination of undigested material from the GI tract

Answer 4

Well, mechanical digestion is the tearing, grinding and mixing of food. Once food enters the mouth, the incisors go to work, tearing the food into smaller pieces. Then the food is moved to the back of the mouth by the tongue. There the chewing goes on. Saliva moistens the food and makes it easier to chew. Once the food has been completely chewed, it is now bolus, a soggy ball of food. The food inside the bolus is already starting to get digested by amylase. Amylase is an enzyme that breaks down starches into simple sugars. An enzyme is a special protein produced by the body. Digestive enzymes help the body break down nutrients into forms that the body can use. The enzyme activity marks the end of mechanical digestion and the beginning of chemical digestion. Do u want 2 know about chemical digestion?... Too bad! That's another question!:-)

Answer 5

Mechanical Digestion are teeth, tounge, and saliva all mix together to get our food in to a wet subance to start digestin.

Answer 6

The chewing of food is the most obvious example of mechanical digestion that occurs inside the mouth. The other kind of digestion is called chemical digestion.

Answer 7

Chewing through the mouth.

Churning in the stomach.
