Summary of this section:
Digestive and Excretory system are just based on how the food and drinks we eat break down in our body and comes out as a waste. When any food goes into your mouth, your body will be able to break down, absorb, and store its nutrients. The four stages of digestive system are ingesting, absorbing, digesting, and eliminating. In your body, many different chemical reactions are occuring which couldn't normally occur at body temperature because they would happen very slowly. An enzyme is a protein found in your body that helps speeds up these reaction. This may sound strange, but your digestive systmem starts at your mouth, and ends at your anus. Any material that can't be absorbed are eliminated in the feces.
