At the beginning of the alimentary canal, food is cut, torn, and ground by the teeth. This mechanical digestion occurs in the mouth, where the incisors slice food, canines tear it, and molars grind it into smaller pieces. Saliva, produced by salivary glands, also aids in moistening the food, making it easier to swallow and begin the digestive process.
