 The digestive system, and oll the system have one or two parts that have meny functions. 
 

For exammple, the large intestine and
the pancres they dont have functions
and they dont have other parts.


For me the mosts importantant part is: 
The small intestine and the large intestine

The function of the digestive system is:

The food goes inside the esofages and pass trough
the small intestine and then through the large intestine.
