8.  The stomach is like a sac where the food is churned and mixed with juices to help digestion.

 

9.  Next the  stomach pushes the food into the small intestine.

 

 

10.  The small intestine is like a 20 foot-long rope. It has many tiny fingers that trap tiny food bits and send them all through the body in the blood stream.

 

11.When all the bits of food have been taken by the body, what is left is called waste.

 

12. This waste moves through the large intestine, sometimes it is called the colon.  All the water is taken out of what is left.  It is packed together so it can pass out of the body.  It looks gross.  You might call it feces, or in our house, poo.
