In brief: Size does matter

This means that the passage of oxygen and carbon dioxide from the lungs to the blood is slightly lower than what it would be for an average person, but since we are all different sizes and our lungs are also different sizes, "average" usually doesn't apply to most people, especially people who are taller/shorter. This finding means that the lungs are normal when adjusted for that size difference.
