Low levels of oxygen stimulate the kidneys to secrete which hormone?
Erythropoietin
Renin
ADH
Aldosterone
The Correct Answer is A
A. Erythropoietin:
Erythropoietin is released by the kidneys in response to hypoxia to stimulate red blood cell production.
B. Renin:
Renin is secreted in response to low blood pressure, not low oxygen levels.
C. ADH:
ADH responds to high plasma osmolality and low blood volume, not oxygen levels.
D. Aldosterone:
Aldosterone is secreted in response to low sodium or high potassium, and part of the RAAS, not oxygen deficiency.

Correct Answer is D
Explanation
A. Over secretion of aldosterone: Aldosterone promotes water reabsorption, which reduces urine output.
B. Decreased GFR (glomerular filtration rate): This would lead to less urine formation, not polyuria.
C. Activation of angiotensinogen: This ultimately leads to water retention, not increased urination.
D. Deficiency of ADH: ADH (antidiuretic hormone) promotes water reabsorption. Its deficiency (as in diabetes insipidus) leads to excessive urine output.
