does this paragraph use the proper scientific vocabulary I think the heart will beat faster if you are doing physical activity than if you aren’t doing physical activity because when you do physical activity your cells use oxygen and if you use them more like when you do physical activity they need more oxygen so your heart pumps faster causing you to have a faster heart rate.
