Where does digestion begin in the alimentary canal?

Question

Quizplus · Accepted Answer

The alimentary canal is the digestive tube and consists of the primary organs of the digestive system. Those organs, in order, are:
mouth (oral cavity)
pharynx
esophagus
stomach
small intestine
large intestine
rectum
anus
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 also begins in the mouth when food mixes with saliva. Saliva contains the enzyme amylase, which begins the breakdown of carbohydrates.
