* The digestive system is an energy system of our body. It works like a fuel for the body. The human body uses the energy to move and leave the waste behind.
* Excretory system helps animals to get rid of chemical waste otherwise it can prove to be poisonous for the body. With the help of excretory system we can get rid of all chemical waste.
Thus proper care of digestive system and excretory system is necessary.
