How are the nutrients broken down by mechanical digestion? What nutrients are broken down by teeth?

HELP ME PLEASE!

How are the nutrients broken down by mechanical digestion? What nutrients are broken down by teeth?
your teeth break food into smaller pieces, then you swallow and the smaller pieces of food pass into the stomach, here


stomach acids breakdown the food into a thick substance called chyme, a small amount of absorption of nutrients occurs in the stomach, the chyme is then moved into the small intestine, and here stomach enzymes breakdown the chyme into small molecules which then are absorbed into the bloodstream.
