Which of the following is a part of the buccal cavity?

The buccal or oral cavity is a term used to refer to the component organs of the mouth that helps us to chew food. The jaws are the muscles comprising the upper and lower jaws that help in the movement of the teeth. Teeth help cut down the food into smaller pieces to make it easy to swallow. The tongue and the cheeks covering the jaws work together to make the food into a paste by mixing saliva with the broken food particles. The buccal cavity is where the digestion process begins. The action of saliva and enzymes on the food makes it softer.
