Correct Answer is A

Explanation

A. Decreases the reabsorption of water: Most diuretics act by preventing the reabsorption of sodium and water in the nephron, increasing urine output.

B. Decreases GFR (glomerular filtration rate): Diuretics do not usually decrease GFR; some may slightly increase or maintain it.

C. Activates the renin-angiotensin-aldosterone system: Diuretics often reduce blood volume, which might trigger RAAS as a compensatory mechanism, but activation of RAAS is not the drug’s direct action.

D. Causes the release of ADH: Diuretics counteract the action of ADH by promoting diuresis.

A. Large intestine, excretion B. Pancreas, release of hormones C. Small intestine, absorption D. Gallbladder, production of bile

Correct Answer is C

Explanation

A. Large intestine, excretion: The large intestine mainly absorbs water and forms feces; it does not have villi.

B. Pancreas, release of hormones: The pancreas releases insulin and glucagon but has no villi and is not directly involved in nutrient absorption.

C. Small intestine, absorption: Villi are fingerlike projections that line the small intestine to increase surface area for absorption of nutrients.

D. Gallbladder, production of bile: The liver produces bile; the gallbladder only stores it. Villi are not involved.
