    Q.

    Our breathing rate increases and you start to breathe heavily, this happens because

    answer choices

    More blood gets circulated around the body

    We have started to perform a physical activity

    To break down Lactic Acid and replenish energy supplies.

    Our muscles need more oxygen so you breathe deeper and quicker so a supply of oxygen can get to the muscles.
