Question:
Role of heart and the lungs in exercise?
Answers:
the heart circulates blood through your body. the lungs fill this with oxygen. one of they key ingrediants needed for burning calories. without oxygen the muscles you want to move would be unable toget their nutrients and oxygen to perform their tasks.
in excersize, muscles need more oxygen and nutrients than when not excersizing. therefor the hearth increases its rate, to pump more oxygen to the muscles. breathing also increases to get more oxygen into the lungs.
