The tongue and the teeth play the most important roles here in moving the food around and chewing. Chemical digestion involves the chemical breakdown of food by different enzymes and chemicals.
What are the 3 forms of digestion?
Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. Chemical digestion involves breaking down the food into simpler nutrients that can be used by the cells. Chemical digestion begins in the mouth when food mixes with saliva.
What are the major parts of a monogastric digestive system?

What happens if we don’t eat animals?
