Correct Answer is B
Explanation
A. Fallopian tubes: The Fallopian tubes have cilia, not microvilli. Cilia help move the egg toward the uterus.
B. Digestive tract: Microvilli are found on the epithelial cells of the small intestine. They increase the surface area for maximum nutrient absorption.
C. Urinary tract: While some absorptive and secretory functions occur in the nephron, microvilli are not prominent structures throughout the urinary tract.
D. Respiratory tract: The respiratory tract is lined with ciliated epithelium, which helps move mucus, not with microvilli for absorption.
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.
