The Human Mouth. The human mouth is a complex structure that consists of both hard and soft tissues forming a hollow cavity. The mouth anatomy features several components including the jaws, teeth, gums, tongue, palate, cheeks, lips, which all together contribute in making possible the various functions of the mouth.
The mouth, also known as the oral cavity, is the secondary external opening for the respiratory tract. Most normal breathing takes place through the nasal cavity, but the oral cavity can be used to supplement or replace the nasal cavityâs functions when needed.
