AThe follicle cells of the thyroid
BThe smooth muscle of the uterus
CThe tubular cells of the kidneys
DThe chief cells of the parathyroid
Answer & Solution
Correct answer: C. The tubular cells of the kidneys
1. Antidiuretic hormone is released when blood osmolarity rises and the blood needs diluting.
2. Its targets are the tubular cells of the kidneys.
3. There it raises epithelial permeability to water, so more water is reabsorbed from the filtrate.
4. More water returned to blood means less water lost in urine and a lower solute concentration.
5. Uterine smooth muscle is the target of oxytocin, and thyroid follicle cells answer to thyroid-stimulating hormone.
