At high altitudes the partial pressure of oxygen is less than that at the ground level. This leads to

A

low concentrations of oxygen in the blood and tissues

B

high concentrations of oxygen in the blood and tissues

C

release of dissolved gases and formation of bubbles of nitrogen in the blood

D

thickening of blood and tissues

Text Solution

Verified by Experts

The correct Answer is:
A
At high altitudes the partial pressure of oxygen is less than that at the ground level. This leads to low concentrations of oxygen in the blood and tissues of people living at high altitudes or climbers.
