The Digestive System

The Digestive System

Biology class…has it been a while for you too?  I remember thinking in class how fascinating and amazing that there were so many things that our body does automatically.  The Digestive System is no exception.

Here is a three question quiz to test how well you paid attention in class (answers on bottom):

  • Our digestive system is made up of the gastrointestinal tract (GI tract for short – it’s made up of hollow organs), and the solid organs: ____, _____ and _____
  • The GI tract starts with the mouth and ends with the anus. What are the four organs in between?
  • What is the average length of the GI tract in adults?

Extra credit: The “GI tract” and “digestive tract” are the same thing.  What is another name for it?  Hint: it starts with an “A”

 

The answers are below…no cheating!
