A species that has a normal resting systolic blood pressure of >260 mm hg. what is a reasonable conclusion based on this info
Kipish [7]

The answer is B. This the systolic pressure of a giraffe in comparison to that of a human that is 100 mm Hg. This high blood pressure ensures that the giraffe maintains 100 mmHg in the brain. Since a high BP impairs gas exchange and increases transpulmonary filtration, the pulmonary circulation must be separated. Therefore, in the giraffe, there is a relatively great difference between the right ventricular and left ventricular maximal rates of pressure ascent, the left ventricular rate of ascent being 5 times that calculated for the right ventricle.
