2. Follow along with your Organ System Chart to record the basic description and function of each system.

3. What is homeostasis?

4. The internal human body maintains homeostasis and/or is homeostatic.

5. What is homeostatic or homeostasis?
Stable despite changes in the outside environment.

6. How do we maintain homeostasis?
Major body systems provide cells with oxygen and nutrients and remove toxic waste products such as carbon dioxide.
