Fear causes the release of adrenaline, also known as epinephrine, which has several physiological effects on the body including heart rate.
Vessel diameter can change quickly through casconconstruction or vasodilation. Most of the peripheral resistance occurs in arterioles (the small vessels of the arterial system). When these smooth muscles contract or relaz, peripheral resistance is either increased or decreased.Source: Modern Anatomy & Physiology by Ateegh Al-Arabi
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
