Digestion Questions -- Study for the quiz! Play a game!

(Scroll down through this quick reading for the game.)

Teeth chew up our food. Saliva from our tongue breaks the food up even more so it will slide down our throat.

Our throat has a food tube inside called the esophagus. It moves the food down into our body by a muscle motion called peristalsis.

After food goes through the esophagus it goes into the stomach. The stomach has chemicals inside it which break up the food into invisible pieces.

From the stomach the food parts go into longer intestine tubes. Intestines clean the food pieces so they can move into the blood and become energy.

There are two kinds of intestines, the small and the large. The small intestine is long and thin -- 20 feet long, in fact! The large one is thick and short.

The colon is part of the large intestine. It gets rid of our food trash when we go to the bathroom.
