Anatomy Question
The β-adrenergic receptor antagonist would affect the sympathetic nervous system, also known as our “fight or flight” response. These β-adrenergic receptor antagonists would block β1 and β2 receptors, which would lower the number of contractions and dilate the blood vessels. This will cause a decrease in cardiac output, which would decrease blood pressure. A decrease in blood pressure will stimulate the firing of baroreceptors into the carotid arteries and aortas, which stimulates the sympathetic response. But since the beta-blockers are present, it blocks the effect of the baroreceptors. This results in light-headedness and dizziness.
