Answer:
An increase in the rate of oxygen that has been removed from hemoglobin could increase the supply of oxygen by the cardiovascular system.
Explanation:
Hemoglobin is a protein, present in the cardiovascular system, whose main function is to remove oxygen from the lungs and take it to the tissues of the human body. Therefore, the more oxygen is removed from the hemoglobin, the greater the oxygen supply. This applies even in the situation presented in the question above, where cardiac output did not increase in the same way as oxygen consumption. In this case, if oxygen consumption is high, the removal of oxygen from the hemoglobin must be increased to supply this consumption.
