List the factors that contribute to total peripheral resistance.

Question

Quizplus · Accepted Answer

Total peripheral resistance is primarily determined by vascular resistance, which is affected by vessel length, vessel luminal diameter, blood viscosity, and turbulence. Heart rate and blood pressure, as well as SNS, PNS, and hormonal stimulation, can affect peripheral resistance indirectly by influencing vessel diameter or blood viscosity, but they are not direct contributors to total peripheral resistance. Arterial pressure, capillary pressure, and venous pressure are important factors in regulating blood flow but are not direct contributors to total peripheral resistance. As for choice D, the listed factors are all related to cardiac output rather than peripheral resistance.
