Third portion of the small intestine, approximately 11 feet long, which connects with the large intestine
Second portion of the large intestine. It is divided into four parts: Ascending, transverse, descending, and sigmoid
Last portion of the large intestine, approximately 8 to 10 inches long, extending from the sigmoid colon to the anus
Sphincter muscle (ringlike band of muscle fiber that keeps an opening tight) at the end of the digestive tract
Produces bile, which is necessary for the digestion of fats. It performs many other functions concerned with digestion and metabolism.
Common Bile Duct
Conversion of the hepatic duct and cystic duct forms this which conveys bile to the duodenum
Produces pancreatic juice, which helps digest all types of food and secretes insulin for carbohydrate metabolism
Small pouch, which has no function in digestion, attached to the cecum. AKA vermiform appendix
Abnormal condition of (multiple) polyps (in the mucous membrane of the intestine, especially the colon; high potential for malignancy)
Inflammation of the liver associated with (excess) fat; (often caused by alcohol abuse and over time may cause cirrhosis)

Gastroesophageal Reflux Disease
The abnormal backward flow of the gastrointestinal contents into the esophagus, causing heartburn and the gradual breakdown of the mucous barrier of the esophagus

Periodic disturbances of bowel function, such as diarrhea, and/or constipation usually associated with abdominal pain
A tumorlike growth extending outward from a mucous membrane; usually benign; common sites are in the nose, throat, and intestines.
Inflammation of the colon with the formation of ulcers. The main symptom is bloody diarrhea. An ileostomy may be performed to treat this condition.
Creation of an artificial opening in the colon (through the abdominal wall). (Used for passage of stool. This creates a mouth-like opening on the abdominal wall called a stoma)
Creation of an artificial opening into the stomach (through the abdominal wall). (A tube is inserted through the opening for administration of food when swallowing is impossible.)
Creation of an artificial opening into the ileum (through the abdominal wall creating a stoma) (Used for passage of stool.)
