12 Low concentration of
oxygen in the blood and
tissues of people living at high
altitude is due to​

Answer 1

Answer:

Low concentration of oxygen in blood and tissues of people living at high altitudes is due to low atmospheric pressure. Because at high altitude, the partial pressure of oxygen is less than at the ground level. This decreased atmospheric pressure causes the release of oxygen from the blood.

Answer 2

Answer:

The reason is that as higher and higher you go the air becomes thinner(Quantity of air decreases) due to the atmospheric pressure and weight of air.

Since the amount of air is less on high altitude so oxygen concentration is low.

But yes to maintain the oxygen concentration in the blood the number of red blood cells increases.

So in a person living at high altitude the no. of RBCs are more that the person living at low altitude
