Question

There is an increase in number of RBCs at higher altitudes to compensate for

• A. High rate of destruction
• B. Lower turn-over
• C. Low level of oxygen
• D. Higher requirement of energy

Answer 1

Answer: (C)

Low level of oxygen

At higher altitudes, the pressure is low due to this oxygen levels are low. When the body doesn't get enough oxygen To compensate for the decrease in oxygen, erythropoietin hormone triggers the production of more RBC to aid in oxygen delivery to the muscles. Hence there is an increase in the number of RBC'S at higher altitudes to compensate for the low level of oxygen.

So, the correct answer is 'Low levels of oxygen'.
