What is the Digestive System?

The Digestive System is the system in which the food that you eat goes through. It consists of the Mouth, Esophagus, Stomach, Liver, Gall Bladder, Pancreas, Large and Small Intestine, Appendix, Rectum, and Anus. There are 2 types of digestion: Mechanical and Chemical. Mechanical digestion is when you chew the food. The food is then broken down by the saliva which is chemical digestion. The following steps of the Digestive System are chemical.

Levels of Organization


The Digestive System relates to the Excretory System because both cleanse the body of wastes. It interacts with the Endocrine System because when the waste or gas enters the Rectum, it sends a message to the brain. The Respiratory System and the Digestive System both include the mouth.


Homeostasis is when the body responds to a change in temperature. The average body temperature is around 98.6*F. If this were to raise, the body would produce sweat, cooling the body down. If the temperature was to drop, the body would begin to shiver. These quick motions would warm the body up. Homeostasis is vital to the survival of the cells.
