What is the main function of the digestive
system?

• Like any other physiologic process, proper
  function or functions of the digestive system
  requires robust mechanisms for control and
  communication. Maintaining adequate control
  requires intimate participation from both the
  nervous and endocrine systems, and the
  gastrointestinal tract has built-in versions of
  both. One consequence of the complexity of
  digestive control systems is that many digestive
  diseases are associated with dysfunction in these
  relationships.

• First the mouth starts everything. When you smell
  something tasty your mouth will start to make
  saliva.Then comes the esophagus.The tongue slowly
  pushes the food down your esophagus. Next is the
  stomach. The food bits that go to the stomach get
  ground down to even smaller peaces. Then it goes
  down the small intestine which is about 22 feet
  long. The liver is next. Your liver is like a
  filter. It filters the blood and sorts it too.
  Last it goes to the large intestine.It is rounder
  then the small intestine which is connected to
  the appendix.
