1.Mouth
The mouth consists of teeth,saliva and the tongue.
Teeth/incisor is used mainly for chewing big pieces of food into smaller bits,making it easier for digestion to take place and easier for us to take in the nutrients of the food. The canine is used to hold the food and tear it apart.
Saliva, a liquid produced by the mouth is a great help in digestion. It also lubricates the mouth, protecting the teeth and the tongue.
Tongue is a muscle in the mouth that manipulates the chewing and swallowing, which affects the rate of digestion. The tongue has taste buds to make out which food is fresh and which one is not.
