Which of the following correctly describes the role of the mouth in the digestive system?
The mouth acts like a muscular bag by churning the food and producing enzymes that aid in chemical digestion.
The mouth produces all of the enzymes needed for digestion and these enzymes are swallowed, which moves them through the digestive tract.
The mouth begins the process of digestion by mechanically breaking food into smaller pieces.
