Index – Where Do You Want To go?

The Mouth The Mouth is used to chew and grind up your food into smaller pieces.

The Esophagus TTTThe esophagus is the tube that carries food, liquids and saliva from your mouth to the stomach. You may not be aware of your esophagus until you swallow something too large, too hot or too cold. To the Stomach! Up, up and away!!

The Stomach TTTThe stomach is an organ of digestion. It has a saclike shape and is located between the esophagus and the intestines. From here we go to the Small Intestine!

The Small Intestine The small intestine lies between the stomach and the colon. The small intestine is about 6 m (20 ft) long. Its primary function is to digest and absorb nutrients. The small intestine makes up more than 70% of the length and 90% of the surface area of the gastrointestinal (GI) tract. The Large Intestine

The main function of the large intestine is to transport waste out of the body and to absorb water from the waste before it leaves. Last stop, the Rectum! ALL ABOARD!

The Rectum The last 6 to 8 inches of the large intestine. The rectum stores solid waste until it leaves the body through the anus. The word rectum comes from the Latin rectus meaning straight (which the human rectum is not).
