The breathing center in the brain is most sensitive to the?
levels of carbon dioxide in the blood. When carbon dioxide levels rise, the breathing center stimulates the muscles of respiration to increase breathing rate and depth. This helps to eliminate excess carbon dioxide and restore a balance in blood gas levels.
What factors are most important in triggering the changes in breathing rate?
Chemicals - most important are the concentrations of CO2, hydrogen ions and O2 in the blood. Chemoreceptors are located in the respiratory center, the carotid bodies and the aortic bodies which detect the levels. Inflation Reflex- stretch receptors in the visceral pleurae are sensitive to the degree of stretching by the lungs. Higher Brain Centers - Impulses from higher brain centers may affect respiratory center. Body Temperature - an increase in body temp, increases the breathing rate.
