The human mouth (also called oral cavity)
is a wonderfully designed machine with many different parts that operate all together to keep you alive, healthy and happy.
The mouth is one of the key parts of the human digestive system.
The basic parts of the mouth are : The upper jaw, that is part of the skull
The lower jaw, connected with the upper jaw and with ability to
move up-down and from side to side
The teeth and gums The muscles which form the cheeks
The tongue The salivary glands that pour the saliva into the mouth
USE
OF THE HUMAN MOUTH AND TEETH
The human mouth and teeth are used not only for
eating,
but also for formatting the sounds while
speaking
and for the expression of our feelings and emotions.
All the parts of the mouth contribute to performing these actions.
The absence of one or more teeth can cause problems to digesting your food, right speech and good appearance, affecting your physical and mental health.
Reduced flow of saliva creates problems with chewing, swallowing and digesting food.
EATING
AND SWALLOWING
The parts of the human mouth operate like a super mincing machine :
- the front teeth cut the food
- the side teeth tear and shred it
- the back teeth crush and grind it
- the saliva moistens the food and
- the action of the tongue and the cheeks mix it all up so that it is easy to swallow
- tiny pimples on the surface of the tongue, the 'taste buds' tell you what you are tasting.
