Feedback:
Several mechanisms control ventilation. The respiratory center in the medulla oblongata and pons control rate and depth of respirations. The central chemoreceptors in the medulla and peripheral chemoreceptors in the aortic arch also provide a mechanism for detecting abnormalities and signal changes to alter the pH and levels of oxygen in the blood. The other options have an incorrect piece of the triad.
