How is chewing of food helpful in digestion?

Answer 1

Teeth are very important in the digestion because they crush the food. the makes the food smaller in size, so it would be easy for tongue to mix those smaller pieces instead of larger ones. And this crushing or chewing also results in increasing the surface area of food that digested juice can act on, i.e the salivary amylase.

Answer 2

Chewing food helps digestion because it breaks down foods so the stomach doesn't have to do so much work. Saliva helps it to be liquefied and adds enzymes that begin digestion. If we just swallow chunks even without chewing, the food will still be digested but the process would take longer.

Answer 3

It makes swallowing easier; and also certain digestion enzymes are introduced into the food from the saliva at this stage.
