Based on your knowledge of ANS receptors, explain how beta blockers are able to manage conditions such as hypertension (high blood pressure)?
What will be an ideal response
Norepinephrine and epinephrine binds to beta adrenergic receptors on heart muscle cells and stimulate an increase in heart rate and force of contraction. Beta blockers are antagonists of norepinephrine and epinephrine meaning that beta blockers can bind and block their effects, leading to a decrease in heart rate and force of contraction and lowering of blood pressure.
