Question

As altitude increases, atmospheric pressure decreases. For instance, at 18,000 feet you would obtain 29% less oxygen than you would at sea level, which means that less oxygen is diffused into the blood from the lungs. This can lead to altitude sickness, or hypoxia as it is called.

Answer 1

Question subitems:

1. When the climber ascends the mountain before acclimating, __to restore homeostasis within the body.

2. As the climber rehydrates and rests at a basecamp, hemoglobin (Hb) is produced, which is the body's response to the stress. As a result, __

3. When the climber returns to sea level before re acclimating, __ to restore homeostasis within the body.

4. As the climber re acclimates to sea level, hemoglobin is replaced at a lower rate, decreasing hemoglobin concentrations in the blood. As a result,

Explanation:

1) So the equilibrium will shift to release O2

2) The body will try to restore the amount of oxygen in blood so it will produce Hb and shift to the production of HbO2

3) The higher oxygen concentration will trend to increase the formation of HbO2

4)  The equilibrium will shift to the release of O2
