response to exercise

• how does exercise effect the rate of respiration and energy

  The more exercise you do, the more energy is required for muscle contractions, which increases the rate of respiration.
• what goes into the body

  oxygen (from air)

  glucose (from food)
• what goes out of our body

  carbon dioxide (from air we exhale)

  energy (what keeps our body running)
• what happens to our heart rate and our breathing during exercise

  heart rate increases to deliver oxygen and glucose to the cells and remove carbon dioxide more quickly

  our breathing increases the get in more oxygen and remove more carbon dioxide
• how can we prove increase of our heart and breathing rate
