Homeostasis in the digestive system

  • The process of digestion seems simple: Matter moves into the body and continues down a beltlike chain of organs that break it down completely before it leaves the body. Yet the maintenance of such a system is complex and relies on a balance of pH and helpful bacteria to maintain homeostasis. Saliva in the mouth is the starting point of digestion. The stomach, on the other hand, needs to be highly acidic to jump-start the breakdown process as well as act as a defense for the body against any harmful bacteria. To balance things out on the basic side, it is important that the small intestine has a high pH,

Respiratory System

Your respiratory system is made up of the organs in your body that help you to breathe. Remember, that Respiration = Breathing. The goal of breathing is to deliver oxygen to the body and to take away carbon dioxide.



Eating junk food and fast food can hurt your body a lot.

Homeostasis: balance


Eating fruits and veggies are much better for you. Also you can exercise to maintain homeostasis. :)
