    People living at sea level have around 5 million RBC per cubic millimeter of their blood whereas those living at an altitude of 5400 meter have around 8 million. This is because at high altitude.

    A)  Atmospheric 02 level is less and hence, more RBCs are needed to absorb the required amount of O2 to survive

    B)  There is more UV radiation which enhances RBC production

    C)  People eat more nutritive food; therefore, more RBCs are formed

    D)  People get more pollution-free air to breathe and more oxygen is available

    Correct Answer: A

    Solution :

    [a] At high altitudes, the atmospheric 02 level is less and hence, more RBCs are needed to absorb the required' amount of O2 to survive. That is why the people living at sea level have around 5 million RBC/mm3 of their blood whereas those living at an altitude of 5400 meter have around 8 million RBC/mm3 of their blood.
