Which of the Following is the Stimulus for the Release

Question

Which of the following is the stimulus for the release of erythropoietin?
A) Hypoxemia
B) Low blood volume
C) Low plasma pH (acidosis)
D) Infection

Accepted Answer

Erythropoietin is released in response to hypoxemia, which is a low level of oxygen in the blood. This can occur when the body is not producing enough red blood cells or when oxygen levels are low due to high altitudes or lung disease. Low blood volume or low plasma pH levels do not directly stimulate erythropoietin release, and infection may cause a variety of responses in the body but is not a direct stimulus for erythropoietin release.
