Blood pH and cerebrospinal fluid pH are affected by carbon dioxide content. This enables the organism to sense a disturbance in gas levels as O the medulla oblongata monitors pH and uses this measure to control breathing O the brain alters the pH of the cerebrospinal fluid to force the animal to retain more or less carbon dioxide O the lungs sense changes in oxygen concentration, which causes the medulla oblongata to speed up or slow breathing the medulla oblongata directly monitors blood oxygen levels and causes breathing changes accordingly O the brain directly measures and monitors carbon dioxide and causes breathing changes accordingly
