During gas exchange between the alveoli and blood capillaries, oxygen is absorbed by the blood while carbon dioxide is removed. This opposite direction of gas exchange occurs due to difference in the concentration gradient of oxygen and carbon dioxide. difference in the molecular size of oxygen and carbon dioxide. thicker layer of the capillaries. the small surface area of the alveoli. 12. Identify the correct statement about the effect of exercise on breathing rate. The vital capacity of the lungs decrease during heavy exercise. The tidal volume of air at rest is greater than the tidal volume of air during exercise. Fast and deep breathing are the result of demanding less oxygen. Exercise and getting fit makes the lungs efficient. 13.
