Answer:
The digestive system is very important to animal health. Without the digestive system earth might still be lifeless other than bacteria and what not. The digestive system is a system to keep us full and energized. It allows us to chew and swallow our food and let it break down in our belly acid. Then it departs our body through the large, small intestines to then be flushed out to sea.
