Once the bolus leaves the mouth, it moves into the pharynx, where it can be swallowed. The suffix -ase. Mastication permits easier deglutition (swallowing) and faster chemical breakdown in the digestive tract. Digestion is classified into two types: mechanical and chemical. This is where indigestible wastes in the form of feces, are removed from the body. Eating solid foods too quickly can cause problems because you never completely break down the food - you just swallow it whole.
