2-The digestive enzymes created by the pancreas break down and from

foods on the way to the small intestine.

3- breaks food down into nutrients that can be absorbed by blood.

4- digestion - food is chewed, mixed and churned.

5-The main function of the intestines is to break down food and absorb .

6-The intestines break down into main sections, the large and the small intestines.

7-The is made up of very dense cells.

8- digestion - chemical reactions break down food.

9-The secondary part of the liver is to create for making blood clot.
