Receptors in the CNS that detect changes in arterial P_CO2 are actually sensitive to the H⁺ concentration of the brain extracellular fluid.

Question

Quizplus · Accepted Answer

The statement is true. The receptors in the CNS that regulate breathing and blood flow are sensitive to changes in the concentration of the brain extracellular fluid, including the levels of hydrogen ions (pH), carbon dioxide (CO2), and oxygen (O2). These receptors are known as central chemoreceptors and peripheral chemoreceptors. They play a critical role in maintaining the proper levels of these gases in the body and responding to changes in metabolic demand.
