AnsCO2 is formed continually in the body by intracellular metabolic processes After it is formed it diffuses from the cells into the interstitial fluids and blood and the flowing blood transports it to the lungs where it diffuses into the alveoli and then is transferred to the atmosphere by pulmonary ventilation About 12 molL of dissolved CO2 normally are in the extracellular fluid corresponding to a PCO2 of 40 mm Hg If the rate of metabolic formation of CO2 increases the PCO2 of the extracellular fluid is likewise increased Conversely a decreased metabolic rate lowers the PCO2 If the rate of pulmonary ventilation is increased CO2 is blown off from the lungs and the PCO2 in the extracellular fluid decreases Therefore changes in either pulmonary ventilation or the rate of CO2 formation by the tissues can change the extracellular fluid PCO2 TRANSPORT OF CARBON DIOXIDE IN THE BLOOD Transport of CO2 by the blood is not nearly as problematical as transport of O2 is because even in the most abnormal conditions CO2 can usually be transported in far greater See Answer
