The oral cavity is the first part of the digestive tract. It contains the mouth, teeth, gums, the bony roof (hard/ soft palate), the floor of the mouth (under the tongue), and cheeks (buccal mucosa). The main function is to begin the process of digestion. It receives and chews food, and mixes it with saliva to begin the swallowing process. ................
