Respiratory System

2. (2 words)chemoreceptors that detect the changes level of oxygen in the blood, located in the aortic arch
5. (2 words) consists of carotid and aortic bodies and adapts when there is a change in the respiratory system
7. the structure that functions in gas exchange
9. (3 words)“inspiratory neurons” that regulate breathing in a relaxed state
11. not breathing enough, causes a lack of O2 in the body and difficulty in removing CO2 from the body
12. also known as “breathing” in
