Explain why exercise does not offset the detrimental effects of cigarette smoking
?Smoking greatly decreases the ability of the blood to transport oxygen to working muscles. Oxygen is carried in the circulatory system by hemoglobin, the iron-containing pigment of the red blood cells. Carbon monoxide, a by-product of cigarette smoke, has 210-250 times greater affinity for hemoglobin over oxygen. Consequently, carbon monoxide combines much faster with hemoglobin, decreasing the oxygen-carrying capacity of the blood. Chronic smoking also increases airway resistance, requiring the respiratory muscles to work much harder and consume more oxygen just to ventilate a given amount of air. If a person quits smoking, exercise does help increase the functional capacity of the pulmonary system.
