					Stomach and Churning

                 Why?
The stomach churns to digest food – this is
the mechanical breaking down of food (not
the chemical).
                  How?
The wall of the stomach has layers of muscle.
 The churning action is made by the outer
 wall of muscle.
                  When?
Churning is an involuntary action that occurs
 about every 20 seconds.
             Why? (again)
Churning helps mix the food with gastric juice
 to break it up into smaller pieces. Only
 when the food is sufficiently broken up can
 it leave the stomach and move into the
 small intestine.
          If it all goes wrong!!
Dysmotility means ‘slow or unco-ordinated
 movement’ and is when the stomach takes too
 long to empty. Instead of the food moving down to
 the small intestine, it just sits there. As a result,
 you might feel queasy or have a heavy, bloated
 stomach, as if you have eaten a huge meal when
 you have only eaten normally. Sometimes, in bad
 cases, the stomach’s normal churning process can
 almost go into reverse and the food is forced back
 up!!!
