Digestive System-G Tract


The digestive system is very important. This system breaks down food and makes it energy for your cells. The cells take the energy to the blood vessels. If you didn't have cells your body would not work properly only because cells are always working in your body to keep you moving. Also to keep your digestive system working properly prevent germs from getting in your food. Germs in food can cause stomach cramps, vomiting, and diarrhea.

Major Organs

Several organs help with your digestive system. The organs that help the most are the ones we don't think about. These organs are the liver, the gallbladder, and the pancreas. The liver and the gallbladder help digest fats. The liver makes a substance called bile. The gallbladder stores the bile until the digestive system needs it. The gallbladder also sends bile into the small intestine, where it helps break down fat. The pancreas adds digestive juices these juices flow into the small intestine to help break down fat, protein, and starch. The pancreas also makes insulin, which helps the body use and store sugar. Also the liver, too, stores some of the digested food when the body is running low on energy the liver sends out the stored food.

System Functions

The digestive system interacts with other systems in the with the cells. The one system that it really interacts with is the circulatory system. It interacts with this system because there are blood cells that get their energy from the digestive system. The cells are like people in a factory and the digestive is their lunch. So if the cells don't get their energy nothing will go right, the cells will get tired and not produce more cells or help the digestive system do what it's suppose to do. If your digestive system did not turn your food into energy you would not have the energy you need to survive and without energy your body will not work properly. Also if your digestive system didn't have waste disposal you wouldn't have a place to get rid of the fat and things you don't need in your body.


There are many diseases that attack the digestive system. But I want to talk about Chron's Disease. Chron's disease causes swelling and irritation of any part of the digestive system. The most commonly affected is the end part of the small intestine, called the ileum. The cause of Chron's disease is unknown, but researchers believe that it is the result of an abnormal reaction in the body's immune system. Normally the immune system protects people from infection by identifying and destroying bacteria, viruses, or other potential harmful substances. The most common symptoms of Chron's disease is abdominal pain, often in the lower right area, and diarrhea.

Staying Healthy

Wash your hands to prevent germs from getting in your food, this will help your digestive system work properly. Germs can cause stomach cramps, vomiting, and diarrhea. Then you will have to take stomach medicine like Pepto Bismol. If you prevent germs from getting in your food you'll have a better chance of not getting stomach cramps, vomiting, and diarrhea. Also your body needs a balanced diet of carbohydrates, proteins, fats, vitamins, and minerals to stay strong and healthy.

Interesting Facts

  1. One interesting fact is that the digestive system for an adult is about 30 feet long. Isn't that pretty awesome.
  2. Another interesting fact is the digestive system is also called the Gastrointestinal Tract. Gastrointestinal - adjective

In conclusion your digestive system is a big part of your life. Your digestive system is very important because it breaks down food and turns it into energy. So if you ever think you shouldn't eat think again because if you don't eat, your digestive system will not be able to give energy to your cells and your cells will not be able to work throughout your body. Like I said earlier cells are like little people in a factory and the digestive system is their lunch. So they digstive system gives them energy to keep on moving.
