2. How do the circulatory system and the respiratory system work together to allow the body to maintain homeostasis
The respiratory system uses homeostasis regulate your breathing and takes out carbon dioxide out of the blood.
The circulatory system uses homeostasis by delivering oxygen and nutrients through the blood.

3. Respiratory System 
The respiratory system is the system that control your breathing in oxygen and exhaling carbon dioxide
The way the respiratory system uses homeostasis is it regulate your breathing and removes the carbon dioxide in the blood
Respiratory System

4. Circulatory System
The Circulatory system is the system that lets blood flow through the body and to transport nutrients, oxygen carbon dioxide, hormones and blood cells.
The circulatory system consist of the heart, blood lymph node, the blood, and the blood vessels, blood lymph.
The way its uses homeostasis is by delivering oxygen and nutrients through the blood so they can uses other fluids.

5. The lungs
They are two elastic sac the have branching's which is where the air/oxygen get drawn from, so oxygen can pass into the blood and carbon dioxide can be removed the lung help you to breathe inhale and exhale.
The lungs use homeostasis by regulates your breathing helps the body get oxygen. 

6. Heart
The heart muscular organ the pumps blood through the circulatory system this happen by the heart beating the vanes around is the way the heart lets blood flow through the body.
The way it uses homeostasis is it pump blood through the body which can regulate the oxygen level through the body

7. How the system will be affected if they were damaged or destroyed?
The respiratory system if it was damaged it would harm your breathing pretty much chocking if it was eliminated it would stop your breathing in all you would faint or even worse die
The Circulatory system was damaged it would have trouble transporting blood through the body and other nutrients. If it destroyed it would stop that in all it wouldn't be transporting blood to the body and not the brain either you could get disabled or you could even die.
