Process:  - A person breathes in oxygen - The oxygen passes through the bronchial tubes to the lungs - The oxygen is moved into the bloodstream - Circulates through the body - The cells in the body exchange the oxygen with carbon dioxide - The bloodstream carries the carbon dioxide back to the lungs - The lungs expel the carbon dioxide through the nose and mouth.  Perturbation hypothesis: suppose If less oxygen passes though the bronchial tubes happens, how will it affect a SMALLER amount of oxygen being delivered to the blood stream.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A:
yes
