Question

what is the effect of vasoconstriction? multiple choice blood pressure increases heart rate decreases peripheral resistance decreases viscosity increases

Explanation:

Vasoconstriction is the narrowing of blood vessels. When blood vessels constrict, the space for blood flow decreases, increasing peripheral resistance. According to the relationship between blood pressure, peripheral resistance, and blood - flow, an increase in peripheral resistance leads to an increase in blood pressure. Heart rate is not directly decreased by vasoconstriction, peripheral resistance increases (not decreases) during vasoconstriction, and blood viscosity is not directly affected by vasoconstriction.

Answer:

Blood pressure increases
