Which of the following is MOST likely to cause polyuria (excessive passing of urine)?
Decreased GFR (glomerular filtration rate)
Over secretion of aldosterone
Decrease amounts of ADH
Activation of angiotensinogen
The Correct Answer is C
A. Decreased GFR (glomerular filtration rate): A low GFR would reduce urine output, not increase it.
B. Over secretion of aldosterone: Aldosterone promotes sodium and water reabsorption, which decreases urine output.
C. Decrease amounts of ADH: Antidiuretic hormone (ADH) helps retain water. A deficiency leads to diuresis, causing polyuria (as seen in diabetes insipidus).
D. Activation of angiotensinogen: This leads to vasoconstriction and aldosterone release, promoting water retention, not polyuria.

Correct Answer is ["A","C","E","F"]
Explanation
A. Regulate blood volume: Kidneys regulate fluid balance by adjusting urine output, influencing blood volume.
B. Excrete solid waste: Kidneys excrete liquid waste (urea, creatinine), not solid waste; the GI tract handles solids.
C. Role in regulation of blood pressure: Via the renin-angiotensin-aldosterone system (RAAS), kidneys influence vascular resistance and fluid volume.
D. Regulate body temperature: Thermoregulation is managed by the hypothalamus and skin, not the kidneys.
E. Regulate electrolyte content of blood: Kidneys regulate levels of sodium, potassium, calcium, and phosphate in the blood.
F. Role in RBC production: By releasing erythropoietin, kidneys stimulate RBC production in the bone marrow.
Correct Answer is C
Explanation
A. Glycosuria: This is glucose in the urine, often caused by diabetes mellitus, not erythropoietin deficiency.
B. Polyuria: This refers to excessive urination and is unrelated to erythropoietin levels.
C. Anemia: Erythropoietin stimulates red blood cell production, so its deficiency leads to reduced RBCs, resulting in anemia.
D. Oliguria: Oliguria is low urine output often related to renal perfusion issues, not directly to erythropoietin.
