The Large And Small Intestines
The gastrointestinal tract starts at the mouth, travel down the tunnel (esophagus), which connects to the stomach, which then empties into the duodenum, jejunum, and ileum---the three parts of the small intestine (@25 feet). This empties into the colon or large intestine (about 5 feet), which then becomes the sigmoid colon, rectum and out the anus. So, every morsel eaten ...Read more
Digestion: The stomach is responsible for mixing food and preparing it for digestion. The enzymes which break food down into nutrients mix with the food in the duodenum, as does the bile from the liver. The nutrients are absorbed in the small intestine. Everything that is not absorbed travels to the large intestine, where water is absorbed, turning the waste from liquid to solid. ...Read more

Other people can retain their entire intestine length and still have poor function. Historically, adults require about 100cm minimum to function without supplemental fluids or nutrition. However, this depends on presence of large intestine and the valve between the small and large intestine. ...Read more
Common bile duct: Bile is made in the liver and is a by-product of liver metabolism (generally broken down red blood cells cleared from the blood stream). The bile collects in the biliary system of the liver and flows to the larger bile ducts - one for the left and right lobes of the liver. These join as the common bile duct which exits the liver. The duct joins the pancreatic duct and flows into the duodenum. ...Read more

Each test is used based upon the clinical presentation and indication. The least invasive and least expensive are x-ray and ultrasound. They also provide the least information. Ct scan provides a lot of info, but requires more radiation. Endoscopy and surgery have more risks. ...Read more
Infection: Millions of bacteria reside in the large intestine. With rupture, the bacteria leak into the abdominal cavity, creating severe inflammation and potential entry of these bacteria into the bloodstream, leading to sepsis or even death if untreated. Depending on the cause & location of the rupture (and luck), adjacent tissues can potentially "band-aid" the whole; other times, surgery is necessary. ...Read moreSee 1 more doctor answer
