What is the job for the mouth in digestion?

Question

?

Answer 1

Several things:

1. Chewing breaks digested food into smaller parts. This allows a larger surface area over which digestive enzymes can work on food and makes breaking food into its constituent parts much more efficient.

2. Saliva lubricates food which allows digestive enzyme to be dissolved in the aqueous state in which they work best. It also facilitates movement of food through the digestive tract.

3. There are also a few enzymes, such as salivary amylase and lingual lipase, released by structures within the mouth. While they have a much less important role than other enzymes in digestion, they do get things started.

Answer 2

Mouth contain a set of teeth which masticate the food into smaller size. the action of saliva makes the food soft and the enzyme ptyalin act on starch to convert it into maltose overall the food after all these changes becomes bolus to get into the oesophagus and ready for peristalysis movement.

Answer 3

Answer 4

the saliva puts a certain enzyme on it that helps breakdown the food
