Question

multiple choice question
when a person moves from miami to denver, the higher elevation of denver causes which of the following?

• inhibition of erythropoiesis and epo secretion
• inhibition of red blood cell production
• stimulation of epo secretion

Explanation:

At higher elevations (like Denver), atmospheric oxygen is lower. The body responds by stimulating erythropoietin (EPO) secretion. EPO promotes red blood cell production (erythropoiesis) to increase oxygen - carrying capacity. The first option is wrong as EPO secretion is stimulated, not inhibited. The second option is wrong as red blood cell production is stimulated, not inhibited. So the correct effect is stimulation of EPO secretion.

Answer:

Stimulation of EPO secretion
