Digestive System
The digestive system is a group of organs that work together to digest food. This system contains epithelial, connective, nervous, and muscular tissues. An example is it using connective tissue to separate it from other systems. There are two types of digestion, mechanical and chemical. Mechanical digestion is the breaking, crushing, smashing, etc of food. Chemical digestion is when bigger molecules are broken down to become nutrients. There are thirteen main organs to the digestive system. They are the salivary glands, gall bladder, liver, appendix, pancreas. Those are the organs that food does not touch. Then the ones that food does touch are the mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum, and anus; all together, 13. The sub- tabs include information about the organs that food passes through. Information about the ones food does not pass through will be included throughout this page.

Such food, moreover, taxes our digestive organs decidedly less, and, in making us more contented and sociable, produces an amount of good difficult to estimate."~ Nikola Tesla Image one: This is depicting colon cancer. It is showing different sizes of abnormal growth in the large intestine.
Image two: This image shows polyp growth in the female reproductive organs, where it is most common. Image three: In this image, in the right corner it shows inflammation in the lining which is going to cause arte amount of stools. Image four: This is showing pockets on the bowl lining. Image five: This is showing too much acid build up in the stomach, causing it to go back up he esophagus. Image six: This is showing a regular colon versus an inflamed one. "Ulcerative colitis can be cured by the operation, but you cannot cure Crohn's disease."~ Mary Ann Mobley- an American actress salivary glands:
This produces saliva and enzymes that break carbohydrates into sugars.
gall bladder:
The small sac-shaped organ beneath the liver, in which bile is stored after secretion by the liver and before released into the intestine. It also turns fat into bile.
liver:
A large organ that bile to break down fat, store nutrients that aren't needed at that time, and breaks down toxins into harmless chemicals.

In this video, you will learn about the function of the digestive system, the organs involved in it, and how the organs work. It also explains where the food travels to and through what path, and how it is broken up.
Diseases:Colon Cancer- cancer of the large intestine.
Polyp Growth and Irregular Cells- Abnormal tissue/ cells. They can appear in any organ with blood vessels. Irritable Bowel Syndrome- This involves abdominal pain and can result in irregular stools. Diverticulitis- This is harmless, small pockets in the lining of the bowel. GERD (Acid Reflux)- A valve called the lower esophageal sphincter (LES) closes as soon as food passes through it. If the LES doesn't close all the way or if it opens too often, acid produced by your stomach can move up into your esophagus. This can cause symptoms such as heartburn. Crohn’s Disease- This is the inflammation of the digestive tract. Appendix:
A tube-shaped sac attached to and opening into the lower end of the large intestine in humans and some other mammals. Also called vermiform appendix.
Pancreas:A large gland behind the stomach that secretes digestive enzymes into the duodenum. Embedded in the pancreas are the islets of Langerhans, which secrete into the blood the hormones insulin and glucagon.
