as lactate is produced by the muscles from accumulation of pyruvate, the blood buffer bicarbonate takes up the hydrogen from lactic acid and is made into water and CO2. with an increasing production of lactic acid, this process continues to occur, thus increasing the CO2 in the blood. with causes ventilation to increase to rid the body of excess CO2
