Question

How does you body adjust the amount of carbon dioxide in your blood during excercise and why?

Answer 1

Carbon dioxide makes the blood more acidic (lowers the pH).  pH sensors will tell your brain what's going on, and your heart will be stimulated to beat faster and your lungs to breathe more frequently.

The idea here is to expel the carbon dioxide more quickly and get oxygen more quickly.  You need oxygen more when exercising than when resting -- oxygen is used in aerobic cellular respiration which supplies energy to cells.  You're using more energy when exercising than when resting.

Answer 2

breathing rate increases and more carbon dioxode is expelled and more oxygen is taken in!!

this is done through receptors in the brain through a feedback system which identify that co2 levels are high so breathing rate increases...

CO2 is diffused into the cells of the lungs which is why we breathe out to expell of the waste
