Quizplus · Accepted Answer

When the chemoreceptors in the medulla oblongata detect a low blood pH, indicating acidosis, the body responds by increasing the secretion of epinephrine and norepinephrine from the adrenal medulla. This response helps to increase heart rate and blood flow, enhancing the delivery of oxygen and the removal of carbon dioxide, which can help to correct the pH imbalance.
