Process:  - Oxygen enters the body through the mouth or nose - The oxygen travels into the lungs - The oxygen binds to hemoglobin proteins within erythrocytes (red blood cells) - The erythrocytes are pumped through the body by the heart - All cells receive the oxygen.  Perturbation hypothesis: suppose the virus isn't strong enough happens, how will it affect more erythrocytes pumped through body.  Does the supposed perturbation have an effect (direct or indirect) on the process?

no
