yes all refer to same process

Answer 2

Answer:

There are two kinds of digestion:  mechanical and chemical.  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.  Saliva contains an enzyme (amylase) that begins the breakdown of carbohydrates.  (An enzyme is a protein that can catalyze certain biochemical reactions).
