Blood Pressure Depends on _______

Question

Blood pressure depends on _______.
A) blood flow × blood viscosity
B) blood flow × peripheral resistance
C) pulmonary pressure × aortic pressure
D) blood volume × blood flow

Accepted Answer

Blood pressure is determined by the amount of blood that is pumped by the heart and the resistance to blood flow in the blood vessels. Peripheral resistance refers to the resistance of the blood vessels to blood flow and is a major determinant of blood pressure. Therefore, the correct answer is B: blood flow x peripheral resistance.
