When a person is making cardiovascular gains through aerobic activity, they are increasing the amount of surface area in the lungs. This enhancement in capacity allows for better gas exchange, which improves oxygen uptake and carbon dioxide removal. Regular aerobic exercise can lead to adaptations in the respiratory system and cardiovascular efficiency, ultimately improving endurance and overall cardiovascular health.
