what happens inside your body?

Regular physical activity can lower your risk of heart, and circulatory disease by 35%. When you are active, the heart produced by your muscles increases your body temperature ,making you feel warmer.Your heart starts to beat faster, pumping more blood to the muscles you are using. Your heart is also a muscle. If you are active regularly it gets bigger and stronger. Your muscles are working harder so they need more oxygen. You start to breath faster so your blood can pick up more oxygen from your lungs. Your lungs work harder to make this happen. Once your blood has picked up oxygen, it moves to the muscles you are using by giving them the extra oxygen they need.
