Digestive System: Mouth and Stomach

Digestion begins in the oral cavity

Digestion begins in the oral cavity

Digestion of food begins in the (a) oral cavity. Food is masticated by teeth and moistened by saliva secreted from the (b) salivary glands. Enzymes in the saliva begin to digest starches and fats. With the help of the tongue, the resulting bolus is moved into the esophagus by swallowing.
