In the control of respiration, which of the following is NOT TRUE? A. Peripheral chemoreceptors respond to changes in oxygen and carbon diox- ide concentration in the blood B. Chemoreceptors in the central nervous system respond to changes in carbon dioxide concentration in the blood C. Respiration responds to smaller changes in the blood concentration of oxy- gen than carbon dioxide D. Central chemoreceptors are sensitive to changes in the pH of the cerebro- spinal fl uid
Option B. Chemoreceptors in the central nervous system respond to changes in carbon dioxide concentration in the blood is incorrect statement because chemoreceptors in the central nervous system respond to changes in pH as there is no buffer in CSF.
