Answer 1

When a person is making cardiovascular gains through aerobic activity, they are increasing the amount of oxygen delivered to the muscles and lungs. This occurs as the heart becomes more efficient, the lungs improve in their ability to exchange gases, and the vascular system enhances its capacity to transport oxygen-rich blood to active tissues. Over time, regular aerobic exercise results in improvements in endurance, cardiac output, and overall cardiovascular health.
