WebIncreased activity of chemoreceptors caused by hypoxia or an increase in the partial pressure of carbon dioxide augments both the rate and depth of breathing, which restores partial pressures of oxygen and carbon dioxide to their usual levels. On the other hand, too much ventilation depresses the partial pressure of carbon dioxide, which leads ...
