Blood pressure is defined as the product of:: (A) Systolic pressure x pulse, (B) Diastolic pressure x pulse rate, (C) Pulse pressure x pulse rate, (D) Cardiac output x peripheral resistance
Answer is D. D i.e. Peripheral resistance x cardiac output The overall blood flow in circulation of adult at rest is about 5 liter/min which equals to cardiac output because it is the amount of blood pumped by hea per unit time. So Blood pressure = Cardiac output x peripheral resistanceQ or Blood flow (Q) x resistance (R) Venous returnQ = MSFP -- RAP MSFP = Mean systemic filling pressure = Right RAP atrial pressure RVR RVR = Resistance to venous return
