stretch receptors and peripheral chemoreceptors send afferent impulses regarding ventilation to medulla.
Afferents connect chest wall receptors to the medulla. Inhalation istopped as a result of vagal afferents being activated by pulmonary stretch receptors. These receptors, which are more sensitive and detect tiny changes in arterial pCO 2, are found in the brainstem's medulla oblongata. Our respiratory system is constantly controlled by these chemoreceptors, which constantly start negative feedback loops: Ventilation increases in response to an increase in pCO2.Chemoreceptors in the periphery. These receptors, which are found in both the carotid body and the aortic body, notice significant pO 2 changes as the arterial blood supply departs from the heart.
