Which of the following is correct regarding acclimatization? A) At high altitudes, hemoglobin's affinity for O₂ is increased because BPG concentrations increase. B) High-altitude conditions always result in lower-than-normal hemoglobin saturation levels because less O₂ is available to be loaded. C) Decreases in arterial PO₂ cause the peripheral chemoreceptors to become less responsive to increases in PCO₂. D) When blood O₂ levels decline, the kidneys produce more erythropoietin, which stimulates breakdown of red blood cells in the spleen.
