C
Feedback:
Beta-blockers competitively block beta-adrenergic receptors in the heart and kidneys, decreasing the influence of the sympathetic nervous system on these tissues and the excitability of the heart. As a result, it decreases the strength of cardiac contraction, reducing cardiac output, which results in lowered blood pressure and decreased cardiac workload. It does not impact urinary output.
