Trace the pathway of food from the mouth to the anus. In doing
this indicate what role(s) each part of the digestive tract
play(s). Then answer the following:

How much more muscular is the stomach compared to the rest of
the digestive tract? For example, feel the stomach and small
intestine of your preserved rat. Also, compare the slide of stomach
and small intestine cross sections.

How is this difference in muscle mass related to its
function?
