ileostomy
The term for forming an opening between the stomach, small intestine, and colon is gastrojejunocolostomy.
The opening of the stomach into the small intestine is called the pyloric sphincter. It regulates the flow of partially digested food from the stomach to the small intestine for further digestion and absorption of nutrients.
The opening between the stomach and the small intestine is called the Pyloric Sphincter- it is a ring of muscle that contracts when the stomach is full, to seal off the opening to the small intestine whilst foodstuffs are liquified in the stomach. When this has been done, the sphincter muscle relaxes, re-opening the channel to allow the liquified nutrients into the intestines.
It compared in size to the large intestine it is about twice as small
Stomach has 2 opening. - cardiac orifice opening of oesophagus into stomach - pyloric orifice opening between stomach and small intestine
The small intestine doesn't usually get sucked into the large intestine, but parts of the small intestine can telescope into itself. This is called intussusception.
The opening between the duodenum and the stomach is called the pyloric sphincter. It regulates the flow of partially digested food (chyme) from the stomach into the small intestine.
The first portion of the small intestine is a small curved portion called "duodenum".
The small intestine
The liver has a duct, called the common bile duct, that delivers bile through an opening into the small intestine, the duodenum, called the major duodenal papilla. This duct is joined by the pancreatic duct as they both transport their products into the small intestine.
It is to create an opening in the abdomen to empty the small intestine
It is the opening from the stomach into the duodenum (small intestine).
