TPR Total Peripheral Resistor

Total peripheral resistance is a measure of the Strömungswiderstand that all Gefäße oppose to the Heart. The arterioles are 50 percent involved in his education. It is composed of the length and diameter of a vessel and the viscosity of the blood. Understandably, the TPR changes depending on these parameters. Any change in the arteriol resistance will therefore have a strong effect on the TPR. The organism takes advantage of this by regulating blood pressure primarily via the arterioles.
