A medical student is studying how the volume of blood in the circulatory system affects blood pressure. He measures the blood volume and pressure of two classmates, a man and a woman. He finds that the man has a higher blood volume but a lower blood pressure than the woman. He concludes that a person with low blood volume would tend to have high blood pressure. What additional factors should the student consider that would most likely affect blood pressure?
