Low concentration of oxygen in the blood ndtissues of people living at high altitude is due to…….

A

low temperature

B

low atmospheric pressure

C

high atmospheric pressure

D

both low temperature and high atmospheric pressure

Text Solution

Verified by Experts

The correct Answer is:
B
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. Low blood oxygen causes climbers to become weak and unable to think clearly , symptoms of a condition known as anoxia .
