The mouth: takes in the food and the teeth inside crush the food into small Pieces and the saliva softens the food and then the tongue pushes the food into the Pharynx.
Pharynx: The Pharynx is responsible for passing the chewed food into the Esophagus with its strong muscles inside of it. It also takes a part of the respiratory system. Why? Well It takes air from the nostril and passes it into the larynx. So the Pharynx has to functions, Switches between getting food into the stomach, then into delivering air to your larynx!
Esophagus: An Esophagus is a a long tube in your body that is very muscular. It connects from your
Pharynx to you Stomach. The Esophagus carries chewed foods to the stomach.
Stomach: Again this organ is a muscular sac. Like most of the people when you put your fists together
you form the size of your stomach. This organs job is to store all of the food that goes down the Esophagus.
The reason Why is the food stores there so the food in the intestines can digest properly. The Stomach
also has something called Hydrochloric acid enzymes. They continue the digestive system that starts in the mouth.
Small Intestines: The Small Intestines is a long tube that is about 1 inch in diameter and about 10 feet long. The organ
is located just to the right of the stomach. All of the intestine is coiled like a hose, and the inside is filled with
Ridges and folds. The folds in the intestine is used to maximize the digestion of the food and to absorb the
nutrients. By the time the food leaves the intestine around 90% of the nutrients in the food is absorbed.
Liver: This organ sorta looks like a triangle but who knows. This organ is an accessory organ of the digestive system
located right of the stomach. This organ weighs about 3 pounds and is the second largest organ in your whole body!
The liver has many functions but its main function is for the Digestive System. Its job is to make the production of
bile and its secretion into the small intestine.
Gall Bladder: This organ is a pear shaped organ, it's located to the posterior of the liver. The Gall Bladders job is to
Store the excess bile from the food in the Small Intestine so it can be reused in the digestion of subsequent meals.
Pancreas: This organ is large and located to the inferior and posterior of the stomach. It's about 6 inches long and looks
like a snake with a lump for a head. "The pancreas secretes digestive enzymes into the small intestine to complete the
chemical digestion of foods."
Large Intestine: The large intestine is a big tube that is about 2 1/2 in diameter and 5 feet. The large intestines function is
to take most of the water from the food that may contain symbiotic bacteria that help take the water out of the food and help take the
nutrients from the food.
That's all the functions that u need to know! If you want to watch the ways it goes down watch this video!

Disorders/ Diseases D;

Info: http://www.digestivesystemdisorders.com
Heart Burn: Probably everyone gets Heat Burn from time to time. This is caused by gastric acid that is from the stomach that flows up into the esophagus.
Diarrhea: Diarrhea is something called a watery stool. Diarrhea is caused by a short-term or long-term bacteria or viral infection.
If long-term diarrhea it may lead to a function disorder or intestinal disease.
Lactose Intolerance: People with Lactose Intolerance is people that lack an enzyme that is called lactate. This enzyme is needed to
Digest something called lactose. Lactose sugar is found in milk products like regular milk! Injuries and disorders in the small Intestine
may lead to this disorder. Some of the symptoms are: Cramping, Bloating Gas, Diarrhea, and nausea.

Staying Healthy

One of the ways you can keep your digestive system healthy is to eat vegetables. Vegetables contain fiber, which fiber helps materials pass through the passages of the Digestive system. It also help bulk up your stool. You should actually eat 30g of fiber a day. This rich balance of food helps prevent Heart Disease, Diverticular Disease, and colorectal disease. You can also eat less processed foods like chips, coke, etc. They contain harmful material like salt,fat etc. And always drink a lot of regular water. It helps with nutrients and it also encourage passages through the digestive system and soften stools. Another way too keep your Digestive system healthy is to quit smoking if you do smoke. Smoking lowers pressure against the junction between the stomach and esophagus. Which makes stomach acid rise up into the esophagus, which may makes you have Heart Burn, Cancer, etc.
