According to the Red Cross, the following hemoglobin ranges are normal:
males: 13.5-17.5 g/dl
women: 12.0-15.5 g/dl
What could be the reason why men tend to have a higher hemoglobin than women? For example, isn't it true that a smaller person will have a larger surface area per unit mass than a taller person of similar build, so the smaller person would have to be able to oxygenate more tissue per unit of blood? And also the uterine lining would probably require a rich oxygen supply as well? Or maybe body composition differences account for the different ranges?
