How may the body acclimate to severe hypoxia?
What will be an ideal response?
Answer: The body may:
- Increase ventilation
- Stimulate erythrocyte synthesis, which results in increased hemoglobin concentrations in the blood
- Increase DPG levels leading to higher oxygen unloading levels in the tissues but also potentially impair oxygen loading in the lungs
- Increase skeletal muscle capillary density, number of mitochondria, and muscle myoglobin
- Decrease plasma volume to increase hemoglobin concentration in the blood
