Your body requires more oxigen as you exercise (to oxigenate muscles while they perform their work), thus your heart pumps faster to get blood circulating faster and which also requires your lungs to bring in more oxigen to your blood.
Why does you heart rate and breathing rate increase when you exercise?
Because your body burns more oxygen for energy (breathing) and the oxygen is pumped in the blood to your body (heart). The blood needs to be pumped faster because it%26#039;s being used faster, and you need to breath faster to get it in you.
