Hi my name is Catherine Jacobus reporting for JC News And I am Jason Carlson Today we will be talking about the Digestive System and how it works. There are many parts of the Digestive System including the esophagus, stomach, pancreas, large intestine, small intestine the liver, and the gallbladder. This system has three main functions. These are, to brake down foods into molecules the body can use, then the molecules are absorbed into the blood and carried throughout the body, and it eliminates waste from the body. The most important part of the Digestive System is the small intestine. Its main job is to take the food that’s been broken and turned into thick liquid and chemically digests it, also it is the main place for absorbing nutrients. Next, I am going to talk about the liver. The livers main job is to produce Bile, which is a substance that breaks up fat particles. Bile flows form the liver to the gallbladder, which Jason is going to talk about now. The gallbladder basically just stores bile and takes the bile after you have eaten and pushes it to the small intestine. Next I'm going to talk about the pancreas. The pancreas's main job is to produce the enzymes that flow to the small intestine and break down starches, proteins and fats. These enzymes also are proteins that speed up chemical reaction in the body. There are many types of enzymes in the body that do this. Next I am going to talk about the large intestine. The large intestine is 1.5 meters long and takes material such as water and undigested food and as the material flows through water is spread through the blood stream. The remaining material leaves the body through the rectum or the anus. The esophagus is the long tubing passageway that carries your food from your mouth to your stomach. Jason is going to talk about that next. When food leaves the esophagus, it enters the stomach. the stomach is a J-shaped pouch made of muscle, as you eat, it expands to be able to hold all of the food. Most mechanical and chemical digestions occur in the stomach. There are some diseases that are fatal or very dangerous such as colon cancer which is a cancer of polyps in the colon and can be cured if detected early enough. It can also get very bad and spread to other organs in the digestive system. Also, GERD or gastrophageal reflux disease is another disease that is rarely fatal but very painful. What happens is acid from your stomach comes up the esophagus burning is and can lead to bleeding of the esophagus. What usually has to happen is you have to take many medications and have surgery just to keep GERD stable. All in all, the digestive system has many very importand parts that all do a very big job in order to keep our body's f unctioning. i am Catherine. And i am Jason reporting for JC news
