There is a bilayer of muscles in the intestines called the muscularis externa. There is an inner circular layer and outer longitudinal layer. These two layers are responsible for the slow regular propulsion of food called peristalsis.

Which part of the body connects the jejunum to the stomach?

There are 3 parts to the small intestine: the duodenum, jejunum and ilium(in that order after the stomach). The duodenum is the first part of the small intestines. It is relatively short (12 inches) and starts at the pyloric sphincter of the stomach, and connects it to the jejunum.

Peristalsis occurs mainly in the gastrointestinal tract, where it helps propel food along the digestive system through rhythmic contractions of the smooth muscle tissue in the walls of the organs, like the esophagus, stomach, and intestines.


What organs respond to the chemicals in food?

Mainly your large intestines, but some in the stomach as well. Your stomach will break down the food so it can move on for more complex digestion. It is your large intestines that do most of the absorption of chemicals and nutrients into your blood, which then moves onto your brain. Some substances that are considered dangerous for our body, like alcohol, are sent to pass through our liver first, which tries to keep as much of the foreign chemical from getting into our body as possible.


What are the enzymes produced by the esophagus?

Name the valve that controls movement of material between the small and large intestines?

The valve between the small and large intestines is the ileocecal valve. The ileocecal valve is a sphincter muscle and its function is to allow the passage of digested food from the small intestine into the large intestine, as well as preventing the reflux of the contents of the large intestine back into the ileum (the last part of the small intestine).
