You conduct a study with mice to determine whether giving them air with a higher than normal oxygen level results in their having a higher than normal oxygen content in their blood. What vessel should you draw blood from if you want to measure the highest potential level of oxygen content in the blood?

B)pulmonary vein
C)pulmonary artery
D)aorta
