Which of the following kidney functions contributes to the production of red blood cells?
Releasing stored bicarbonate
Producing and secreting erythropoietin
Stimulating conversion of angiotensinogen
Activating vitamin D
The Correct Answer is B
a. Releasing stored bicarbonate: This function helps regulate acid-base balance but is not related to red blood cell production.
b. Producing and secreting erythropoietin: The kidneys produce and release erythropoietin, a hormone that stimulates red blood cell production in the bone marrow.
c. Stimulating conversion of angiotensinogen: This is part of the renin-angiotensin system, which regulates blood pressure and fluid balance, not red blood cell production.
d. Activating vitamin D: This function helps in calcium and phosphate metabolism but is not directly involved in red blood cell production.
