Introduction
why is the digestion system so important?
Well you came to the right place to learn about the digestion system.When you eat food your teeth will sofen it so it can go down the esophagus which is a big,long tube that helps your food go to your stomach.

Major organs

The main organs of the digestive systemare the mouth, large intestines, small intestine, stomach, gall bladder, liver and pancrease. Digestion
System Functions
The food you eat goes in through the mouth and will be moved through the digestive tract to be broken down. The digestive tract ,a series of hollow organs connected by tubes from the mouth to the anus, including the mouth, esophagus, stomach, small intestine, large intestine, colon and rectum. Each of these organs propel food and liquid through the digestive system.
The digestive system contains glands that produce enzymes to aid in the digestion. The salivary glands in the mouth produce saliva that begins to break the food into smaller pieces. The stomach produces stomach acid that breaks down the proteins. Once food reaches the small intestine, other digestive juices produced by the pancreas and liver allow for the breakdown of carbohydrates, fats and proteins.
Not only must the digestive system break down the food, it is also responsible for absorbing the nutrients. This absorption takes place in the small intestine, which contains small fingerlike projections called villi. The presence of these villi increases the surface area, allowing more nutrients to be absorbed.





Diseases

These are common terms and their definitions associated with the gastrointestinal system and digestive problems or diseases:
Amylase: Enzyme produced in the pancreas and salivary glands that helps in the digestion of starches from the diet. Blood amylase levels may be increased in patients who have pancreatitis or salivary problems like Sjogren’s disease.

**Amyloidosis** : A group of diseases that results from the abnormal deposition of a protein called amyloid in tissues and organs.
Bezoar: A clump of food or hair in the digestive tract. Bezoars can cause obstructions in the stomach that keep food from passing into the small intestine.
Celiac disease: A disease resulting from the abnormal reaction by the body's immune system to gluten, a protein found in grains such as wheat, rye, and barley and other foods. In people who have celiac disease, the immune system causes damage to the small intestine and prevents the proper absorption of nutrients from food. Symptoms include diarrhea, anemia, and weight loss.
Elastase: An enzyme found in fluids produced by the pancreas. It aids in the digestion of several proteins, including elastin, an elastic substance in the lungs and other organs that is part of their structural framework. Normally, elastase is inhibited by a substance called alpha-1 antitrypsin.
Electrogastrography (EGG): A diagnostic test that measures electrical activity in the stomach using electrodes placed on the skin.
Endoscopy: A procedure that uses a flexible, lighted tube to look inside the body. The instrument is introduced into the body through a natural opening like the mouth or anus.
Endoscopic retrograde cholangiopancreatography (ERCP): Procedure in which a tube is placed down the patient's throat, into the stomach, then into the small intestine. Dye is injected and the ducts of the gallbladder, liver and pancreas can be seen on X-ray. The procedure may be performed to diagnose and treat problems in the liver, gallbladder, bile ducts, and pancreas, including gallstones, inflammatory strictures (scars), leaks (from trauma and surgery), and cancer.
Gastrin: A hormone that causes the stomach to produce acid, too much of which can cause stomach and duodenal ulcers.
Gastrinoma: Tumor that develops in the pancreas or duodenum of patients with Zollinger-Ellison syndrome. Gastrinomas secrete the hormone gastrin.
Gastroesophageal reflux: A condition in which stomach acid and contents back up into the esophagus, producing symptoms of heartburn or regurgitation.
Gastroparesis: Paralysis of the stomach. It is a disease in which the stomach cannot empty itself of food in a normal fashion. This can happen in diabetes.
H2 blockers: A group of digestive disease drugs that relieve acid reflux and pain by suppressing the production of stomach acid.

Staying Healthy

Be adventurous, and eat a variety of fruits and vegetables in any form – canned, fresh, frozen, or dried. Plant foods are rich in fiber and many disease fighting chemicals.



Interesting Facts

. An adult esophagus ranges from 10 to 14 inches in length, and 1 inch in diameter.

Conclusion

If we never had the digestive system the we would have waste in our body,our food will go through our body fast and we wouldnt have any body guards for our food(or should i say kidneys) to seprate the waste.So if your reading this go get a snack and it better be healthy so while you are eating this snack i just want to say stay healthy and stay awesome okay and also stay fit.if for some reason you dont understand this project then it read it agian.
