People living at sea level have around 5 million RBCs per cubi millimeter of their blood whereas those livihg at an altitude of 5400 metres have around 8 million. This is because at high altitude
Options
A. people get pollution- free air to breathe and more oxygen is available
B.atmospheric O2 level is less and hence, more RBCs are needed to absord the required amount of O2 to survive
C.there is more UV radiation which enhances RBC production
D.people get more nutritive food, therefore, more RBCs are formed
Solution
At high altitude. the atmospheric O2 level is less and hence, more RBCs are needed to absord 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 livihg at an altitude of 5400 metres have around 8 million RBC/mm3 of their blood.
