WebDec 22, 2024 · For one, the medulla is home to your body’s respiratory center. The respiratory center keeps track of the oxygen and carbon dioxide levels in the blood and adjusts them by increasing your breathing rate. … WebRespiration is controlled by a section of the brain called the medulla. Lying on either side of the medulla are chemoreceptors that sense changes in the level of pCO2 in the blood. When the level of pCO2 becomes too high or too low, chemoreceptors send signals to the inspiratory center within the medulla to increase breathing or slow it.
