Biology - Mechanical digestion in the mouth
Mechanical digestion in the mouth
Teeth mechanically digest food. This greatly increases the surface area of
the food enabling chemical digestion to occur more rapidly.
In humans, there are four types of teeth:
* Incisors
* Canines
* Premolars
* Molars
An adult human jaw has 16 permanent teeth: 4 incisors, 2 canines, 4
premolars and 6 molars.
