Question

A disturbance in oxygen and CO2 levels in the blood can be corrected as _____. A. the brain alters the pH of the cerebrospinal fluid to force the animal to retain more or less carbon dioxide B. the brain directly measures and monitors oxygen levels and causes breathing changes accordingly C. the medulla oblongata, which is in contact with cerebrospinal fluid, monitors pH and uses this measure to control breathing D. bicarbonate anions trigger atrial natriuretic peptide release in cardiomyocytes E. stretch receptors in the lungs cause the medulla oblongata to speed up or slow breathing

Explanation / Answer

Option C

One of the function of the modular oblongata is to monitor the pH in the blood.When there is high amount of CO2 in blood it causes more acidic and if it is low then it becomes less acidic this small change in pH is deducted by the medulla and controls the breathing
