- The mouth contains many other organs-such as the teeth, tongue, and the ducts of the salivary glands-that work together to aid in the ingestion and digestion of food. The mouth also plays a major role in the production of speech through the movements of the tongue, lips and cheeks.

Digestion (1) Mouth: Food is chewed into smaller pieces. Adults have 32 specialized teeth - teeth that can grind, chew, and tear different kinds of food. The tongue is an organ consisting of skeletal muscles (voluntary muscles) that move the food around the mouth to allow for efficient mechanical digestion.

Functions of Teeth A smile is the facial expression that most engages others. With the help of the teeth — which provide structural support for the face muscles — the mouth also forms a frown and other expressions that show on your face. The mouth also plays a key role in the digestive system, but it does much more than get digestion started.

The main Parts of the Mouth Teeth in humans and other mammals are a critical component of the digestive system performing the function of tearing and chewing foods (mastication). They also contribute in speaking by helping in the formation of sounds. Properly aligned bright white teeth are a key asset in a person’s appearance.

- Tongue: Is a muscular organ in the mouth. The tongue is covered with moist, pink tissue called mucosa and tiny bumps called papillae. Thousands of taste buds cover the surfaces of the papillae. Taste buds are collections of nerve-like cells that connect to nerves going into the brain. There are four types of taste buds: sour, sweet, bitter and salty. The tongue is vital in tasting and chewing food and in speech. Smell: Nose: The nose, along with the mouth, lets air in and out of the body. It also helops us distinguish different smells in that air. The nasal root is the top of the nose, forming an indentation at the suture where the nasal bones meet the frontal bone.
