Question

Drugs called beta-blockers ________.

A) decrease heart rate and blood pressure
B) have widespread sympathetic effects
C) increase a dangerously low heart rate
D) are potent antidepressants

Answer 1

Beta-blockers decrease heart rate and blood pressure by blocking the beta receptors associated with vasoconstriction and cardioacceleration.

Step-by-step explanation:

Beta-blockers are drugs that are used to decrease heart rate and blood pressure. They work by blocking the beta receptors associated with vasoconstriction and cardioacceleration. By blocking these receptors, beta-blockers prevent the effect of adrenaline, leading to a decrease in heart rate and blood pressure.
