So not only is the heart filled with more blood to eject, it expels a greater percentage of the end-diastolic volume. If vital capacity expands, your total lung capacity does as well, as you can take fuller, deeper and more oxygen-rich breaths. Even people in good shape may have trouble breathing at high altitudes. and MVV are flow rates so they will be low. What happens in the lungs when the diaphragm relaxes?
