Suppose arterial pCO2 levels increase (as might occur during breath holding). How is respiratory rate and depth changed to compensate for an increase in arterial pCO2 – trace each specific part(s) of the reflex arc involved for peripheral chemoreceptors. Note: a reflex arc consists of a receptor, afferent (sensory) pathway, integration center, efferent (motor) pathway, and effector(s). Discuss the role of central chemoreceptors in control of breathing citing the key differences between the peripheral and central chemoreceptors.
