THE DIGESTIVE SYSTEM
Parotid gland Sublingual gland Submandibular gland Esophagus Stomach Liver Gallbladder Large intestine Small intestine Appendix Rectum Anus
>it causes diarrhea or constipation >constant pain in the stomach, adding discomfort. Those who suffer from a spastic colon may also suffer from frequent urges to defecate and extremely painful spasms during evacuation of the bowel. >symptoms = Diarrhea or constipation Stomach bloating Abdominal cramping Excessive gas. > causes = Muscle and nerve Stress Poor dietary habits
Spastic colon treatment involves a lot of dietary changes and adjustment as well as managing the various symptoms. This may involve avoiding high fat food, sugar, dairy products, meat, alcohol and tobacco products. This means many people will have to make lifestyle changes if they want to solve their colon problem. Spastic colon treatment will probably include lowering the intake of foods that have high fiber like green leafy vegetables, fruits, whole grain bread, whole wheat pasta and legumes such as peas. Beans are very high in fiber; especially black beans.
>peptic ulcer disease refers to the painful sores or ulcers in the lining of the stomach or the first part of the small intestine, called the duodenum. >symptoms = Heartburn Nausea Bloating of the stomach Weight loss >causes = stress spicy food 60% are caused by bacterial infections.
Along with reducing stress and modifying lifestyle, doctors treat ulcers with several types of medicines. If medication is ineffective or complications arise, surgery may be required.
Mouth-to tear and grind food, mechanical digestion, the mouth has 32 teeth
Salivary Gland- 3 pairs, release saliva which moistens food and helps you swallow. It also contains the enzyme amylase which breaks down starch molecules into sugar
Esophagus- swallowing pushes food into esophagus, a tubular passageway to the stomach
Stomach- squeezes, sloshes, and mixes food, adds hydrochloric acid and pepsin which changes food into a thick liquid called chyme
Small Intestine- chemical substances break down complex sugars into simple sugars into proteins into amino acids and emulsify fats.

Pancreas- adds more digestive chemicals to the chyme as the chime travels through the small intestine. Trypsin- breaks proteins into amino acids. These amino acids enter the circulatory system where they are transported to the liver for storage, but some are sent directly to cells.
Large intestine- The last step of digestion is called absorption. It occurs when nutrients pass through the wall of the small intestine and enters the circulatory system. Only waste remains in the small intestine after absorption occurs. They enter the large intestine where water is removed from the wastes and returned back into the body. This process is called reabsorption.
Rectum and Anus- After reabsorption waste collects in the last 4-6 inches of the large intestine. This part of the large intestine is called the rectum. Defecation occurs when waste products are moved through an opening called the Anus.
