Answer to Question 1

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.

Answer to Question 2

B
Feedback:
Bile is an alkaline secretion that is formed continuously in the liver, carried to the gallbladder by the bile ducts, and stored there. Bile salts are required for digestion and absorption of fats, including fat-soluble vitamins. Hydrochloric acid is produced in the stomach and begins the process of digestion. Pancreatic enzymes include chymotrypsin and trypsin that break down proteins, lipases to break down fat, and amylases to break down sugars. Gastric juice includes hydrochloric acid.
