Mean aerial pressure depends upon: (A) Cardiac output, (B) Cardiac output & peripheral resistance, (C) Aerial complaince, (D) Peripheral resistance
Answer is B. Cardiac output and peripheral resistance. As blood is pumped out of the left ventricle into the aoa and distributing aeries, pressure is generated. The mean aerial pressure (MAP) is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP).
