The effects of this hormone oppose aldosterone.
A) ADH
B) oxytocin
C) inhibin
D) atrial natriuretic peptide
E) renin

Question

Quizplus · Accepted Answer

Atrial natriuretic peptide (ANP) opposes the effects of aldosterone by promoting sodium and water excretion in the kidneys, leading to decreased blood volume and lower blood pressure. ADH (choice A) promotes water reabsorption in the kidneys and can actually enhance the effects of aldosterone in retaining sodium. Oxytocin (choice B) promotes uterine contractions and milk ejection, and does not have any known effect on aldosterone. Inhibin (choice C) inhibits the secretion of follicle-stimulating hormone (FSH) from the pituitary gland and does not have any known effect on aldosterone. Renin (choice E) is an enzyme that catalyzes the conversion of angiotensinogen to angiotensin I, which ultimately leads to the release of aldosterone. Therefore, renin and aldosterone have a positive relationship rather than opposing effects.
