WebThe respiratory rate is controlled by the respiratory center located within the medulla oblongata in the brain, which responds primarily to changes in carbon dioxide, oxygen, and pH levels in the blood. The normal respiratory rate of a … 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.

WebIncreased activity of chemoreceptors caused by hypoxia or an increase in the partial pressure of carbon dioxide augments both the rate and depth of breathing, which restores partial pressures of oxygen and carbon dioxide to their usual levels. On the other hand, too much ventilation depresses the partial pressure of carbon dioxide, which leads ... WebDec 26, 2024 · Unconscious breathing is controlled by respiratory centers in the medulla and pons of the brainstem ( Figure \(\PageIndex{4}\)). The respiratory centers automatically and continuously regulate the rate of breathing depending on the body’s needs. These are determined mainly by blood acidity or pH.
