Why does the respiratory system work with the circulatory system?
These two systems work together so they can get blood and oxygen to the body. This is how it works, The air enters the lungs and the lungs transfer oxygen to the heart. Then the heart pumps the oxygen rich blood through the body. Then the oxygen poor cells go back to the heart that then get renewed with oxygen.
Why is the respiratory system important?
The respiratory system is important because without it you would die from lack of oxygen unless your a fish. The respiratory system is made up of your nose,mouth,trachea,lungs,and diaphragm which help you get oxygen to your body.
