Question

how siliva helps in digestion

Answer 1

siliva helps carbo-hydrate digestion

Answer 2

The process of digestion begins in the mouth. Saliva secreted by the salivary glands can convert starch into sugars if allowed to mix with chewed food for some time. To test this take some boiled rice in a test tube and pour a few drops of iodine solution into it. You will see violet color. Now chew some boiled rice well for ten minutes and put it in another test tube.Pour few drops of iodine solution. You will notice no change in color. This is because saliva converted the starch into sugars.
