What is the primary regulator of the magnitude of ventilation in normal circumstances? A) H⁺ concentration of the brain extracellular fluid, which is monitored by central chemoreceptors B) PO₂ of the arterial blood, which is monitored by central chemoreceptors C) PO₂ of the arterial blood, which is monitored by peripheral chemoreceptors D) PCO₂ of arterial blood, which is monitored by central chemoreceptors

Question

Quizplus · Accepted Answer

The primary regulator of ventilation is the H⁺ concentration in the brain's extracellular fluid, which is influenced by CO₂ levels and monitored by central chemoreceptors.
