Transcript of The Digestive System

What is the Digestive sytsem? The digestive system is made up of the digestive tract which is a series of hollow organs joined in a long, twisting tube from the mouth to the anus, with other organs that help break down and absorb food. The main parts in the digestive system are the mouth, esophagus, stomach, small intestine, large intestine—also called the colon—rectum, and anus. How the different parts of the system work together? The parts of the system work in many ways. Food starts and enters the body through the mouth and then makes its way down the esophagus. The food then makes its way to the stomach which then starts to digest the food oncein the stomach. After the it is digested then it passes through the small intestine to the large intestine. From there it carries to the rectum and enters the body at the anus. As food passes through the small intestine the small intestines absorb the nutrients and give it to the liver. Working with other systems When the nutrients are sent to the liver has to send it out to the rest of the body. So the blood vessels of the liver help deliever the nutrients throughout the body with help of the circulatory system. Diseases and the effects Zollinger-ellingson syndrome
