Control of ventilation refers to the physiological mechanisms involved in the control of physiologic ventilation, which refers to the movement of air into and out of the lungs. Ventilation facilitates respiration. Respiration refers to the uptake of oxygen and the removal of carbon dioxide. Under most conditions, the partial pressure of carbon dioxide controls the rate of respiration. The most important function of breathing is gas exchange (of oxygen and carbon dioxide). Thus the control of respiration is centered primarily on how well this is achieved by the lungs. There are four main centers in the reticular formation and other parts of the brainstem that regulate the respiration rate. # Inspiratory centre - reticular formation, medulla oblongata # Expiratory center - reticular formation, medulla oblongata # Pneumotaxic center - various nuclei of the pons # Apneustic center - nucleus of the pons The first two centers are present on the medulla oblongata whereas the last two centers on the pons region of brain. ==Involuntary control of respiration== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Control of ventilation」の詳細全文を読む スポンサード リンク
