Teeth form and function

Molars
-Molars are the big strong teeth at the back of your mouth on either side. They have flat tops with ridges and are good for grinding and softening food. You have two or three pairs of molars on each side.
-The third pair of molars, called wisdom teeth, is the last to grow, and in some people, they never grow at all.

Premolars
-As an adult, you should have two pairs of premolars on each side, they have two edges but like molars they are good for grinding.

Canines
-You have just one pair of canines on each side. They are the big, pointed teeth just behind your front teeth - ideal for tearing food.

Incisors
-Incisors are the flat front teeth, with sharp edges for cutting food. There are two pairs on each side of the mouth.

ESOPHAGUS Food canal connecting hose

This is a hollow muscular tube 10 inches (25 cm) in length with a diameter of one inch. In the neck this food pipe lies behind the wind pipe and in the chest it lies behind the heart.
The wall of the esophagus is made of two layers of muscle the inner circular and outer placed lengthwise.

The food ball is pushed down towards the stomach by the contraction of muscles in the wall of the esophagus.
The food will reach the stomach in about ten seconds. Food will travel down this food pipe when lying down or even if you are standing on your head.
