Why do the heartrate and breathing rate increases with increased activity? by Voon Yen Cheng https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r Group Answer en-us 2020-02-20 12:56:17 UTC 2020-03-12 06:57:28 UTC hello@padlet.com Group A cheng_voon_yen https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447989852 We use energy when we are exercising therefore the heart needs to pump more blood to the lungs and the small intestine to collect digested food and oxygen to make more energy for the body]]> 2020-02-20 13:20:27 UTC https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447989852 Group B cheng_voon_yen https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447990006 We use up energy when we do these activities and more energy will be needed. The heart will need to pump more blood to carry more oxygen and digested food and let the red blood cells give out the substances to all parts of the body so that they can produce more energy.]]> 2020-02-20 13:20:50 UTC https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447990006 Group C cheng_voon_yen https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447990221 We need more energy when we do more activity, and the energy is made from digested food and oxygen, we need the blood to transport it faster so our heart will beat faster. If the blood does not reach the cells, our cell will die so when we are doing more activities, our heart rate will increase and we need to get more oxygen so our breathing rate increases too.]]> 2020-02-20 13:21:15 UTC https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447990221 Group D cheng_voon_yen https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447990593 During exercise, our body needs more energy. Thus, our heart beats faster so as to supply blood that is rich in oxygen and digested food to all parts of the body, which is used in the process of respiration to release energy at a faster rate.Also, we need to remove more carbon dioxide and waste materials away from our body at the same time.

We get our energy from the digested food. Our muscles need more oxygen. To do that, we breath faster for more oxygen to enter the body. Then, the heart must pump faster for the blood to circulate in our body to transport oxygen and digested food to all parts of the body and take carbon dioxide to the lungs as all cells respire.

So higher blood flow is needed to carry more digested food and oxygen to the various parts of the body and muscles.

Our breathing rate increases as we need to take in more oxygen. Our heart needs to pump faster in order to allow red blood cells to transport sufficient oxygen that was taken from the lungs to the other cells in our body.]]> 2020-02-20 13:22:50 UTC https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447991006 Group G cheng_voon_yen https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447991130 we use energy when we are exercising.Therefore we need the heart to pump more blood to allow digested food and oxygen to go to all parts of our body and make more energy for us.]]> 2020-02-20 13:23:04 UTC https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447991130 Group H cheng_voon_yen https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447991209 When we do increased activity,we need to breath more,so we need the heart to pump more blood to carry oxygen to the cells]]> 2020-02-20 13:23:15 UTC https://padlet.com/cheng_voon_yen/eb5a8i4lhb0r/wish/447991209
