Which of the following defines the pressure in the vascular system in the absence of blood flow?
(A) Pulse pressure (B) Critical closing pressure (C) Mean circulatory filling pressure (D) Perfusion pressure
(C) Answer- C. Mean circulatory filling pressureMean Circulatory Filling pressure (MCFP) is equilibrium pressure that is reached throughout the cardiovascular system when cardiac output is stopped completely. MCFP can be measured by stopping blood flow (e.g., by stopping hea pumping by giving shock to hea with electricity) and allowing the pressure throughout the circulatory system to reach equilibrium. MCFP is equilibrium pressure everywhere in circulation.
