Peripheral Resistor

peripheral vascular resistance, resistance of the blood vessels embedded in the tissues, directed against the movement of the blood by heart force, either as total resistance of the entire vascular system lying behind the ventricular outlets, or as resistance of individual current path sections, e.g. the pulmonary circulation, or the supply area of a coronary artery. The peripheral resistance is influenced by the endocrine RAA system, the activity of local RA systems and the sympathetic nervous system.
