A cyclist complained that the lead motor cycle contributed carbon monoxide which affected her performance. High levels of carbon monoxide can decrease an individual's VO 2 max by: binding to hemoglobin to displace oxygen. irritating the bronchioles. decreasing the number of red blood cells. decreasing the arterial PO2 to half its normal value.

What is the biological effect of carbon monoxide (inhaled by smoking) on the body?It binds to haemoglobin more readily than oxygen binds to haemoglobinIt causes scar tissue in the liverIt produces stress hormonesIt causes fatty deposits in the blood vessels

Which of the following is the primary health effect associated with exposure to Carbon Monoxide?Group of answer choicesReduced Oxygen levelsMuscle aches & painsDifficulty speakingDecreased blood flow

An increase in the level of carbon dioxide in the blood will:Question 47Answera.decrease alveolar ventilation.b.decrease pulmonary ventilation.c.decrease the rate of breathing.d.increase the pH of arterial blood.e.increase the rate of breathing.

Which of the followig would increase the pH of the blood?   high intensity exercise resulting in the production of CO2. decreased ventilation causing a build up of CO2. increased ventilation at the lung to remove CO2. a higher ventilation to perfusion ratio (V/Q) in the lung.

All of the following conditions will cause an increase in the circulating levels of carbon dioxide in the blood, EXCEPT:Question 64Answera.anaerobic metabolism.b.lactic acidosis.c.acute hyperventilation.d.increased metabolism.
