Question

Choose the answer which best explains how vasoconstriction can cause increased blood pressure. choose the answer which best explains how vasoconstriction can cause increased blood pressure. vasoconstriction increases peripheral resistance (also called vascular resistance). vasoconstriction decreases cardiac output. vasoconstriction increases cardiac output. vasoconstriction decreases peripheral resistance (also called vascular resistance).

Answer 1

Vasoconstriction cause increased blood pressure by INCREASING PERIPHERAL RESISTANCE, ALSO CALLED VASCULAR RESISTANCE. In the human body, increase in peripheral resistance results in increased blood pressure. When blood vessel constrict, the flow of blood is restricted and the body begin to retain heat, this leads to an increase in the vascular resistance which in turn leads to increase in blood pressure.
