A person with high blood pressure (hypertension) is prescribed a drug that blocks beta receptors. How could this medication alleviate hypertension?
What will be an ideal response?
Blocking the beta receptors on cardiac cells would decrease (or prevent) sympathetic stimulation of tissues containing those cells. As a result, heart rate, force of cardiac muscle contraction, and contraction of the smooth muscle in blood vessel walls would decrease, lowering blood pressure.
