Today my group was investigating our respiritory system and we did tis by taking our breathing rate before and after playing a game of uktimate frisbee. The way we recorded our breathing rate was by counting the amounts of breaths that we took for 10 seconds and then we timesed the amount of breathes we took by 6; the reason for us timesing it by 6 was so that the time we recorded it would be equal to a minute.
In between the two times that we recorded our breathing rates we played a game of ultimate frisbee, Playing ultimately frisbee was so that we could see the diference between a resting breathing rate and a breathing rate after someone has played a game or taken part in activity. We found out that our breathing rate goes up and this is because for us to be able to move we rely on our muscles and our muscles rely on oxygen for them to be able to work, as we were working our muscles at a high intensity our muscles needed more oxygen. Our lungs are under loads of pressure because of them having to supply parts of the body with oxygen; the reason for us breathing more is because our lungs act like a hoover and they such air through our mouths so the process of them supply oxygen for the body can continue.
