Anatomy of the Mouth |
||||||
 |
||||||
|
||||||
| In humans, the mouth is an integral part of digestion, speech, and breathing. Food enters the mouth to be broken down both by the teeth and by enzymes secreted by three salivary glands—the sublingual gland, the submandibular gland, and the parotid gland. The tongue pushes food down the pharynx. The tongue and nasal cavity modify sound waves to produce the sounds of speech, while the tongue and teeth work together to form words. | ||||||
