The specific form of hypoxia experienced at high altitudes is_____________?
Show answer Hide answer
Answer: B. Hypoxic Hypoxia
Explanation
High altitudes feature reduced barometric pressure lowering inspired oxygen tension. Arterial oxygen content drops because alveolar oxygen pressure is significantly decreased. This specific environmental condition is classified clinically as hypoxic hypoxia. Atmospheric pressure decreases with increasing elevation above sea level. Oxygen percentage remains constant at twenty-one percent, but partial pressure falls. Arterial chemoreceptors detect this low oxygen tension and stimulate hyperventilation.
Climbers scaling high mountains experience symptoms of acute mountain sickness. Long-term high altitude exposure triggers compensatory erythropoietin release. Aerobic athletic performance is impaired due to reduced ambient oxygen availability. Anemic hypoxia stems from reduced hemoglobin concentration or functional capacity. Stagnant hypoxia results from inadequate blood flow or circulatory system failure. Histotoxic hypoxia occurs when cellular poisoning prevents oxygen utilization despite presence.
