The mouth is the beginning of the digestive system and plays a crucial role in the process of digestion. It is also an important part of the respiratory system as it is where air enters and exits the body during breathing.
Teeth: Used for biting, chewing, and grinding food.
Tongue: Helps to mix food with saliva and push the food to the back of the mouth to swallow.

Uvula: The small, fleshy piece of tissue that hangs down at the back of the throat.
