Storyboard Text
- Cellular respiration is the metabolic process in which oxygen is used to break down carbohydrates, fats, and proteins to generate ATP. Mitochondria are the 'engine room' of eukaryotic organisms, as they arethe main site of cellular respiration. Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.
- My heart pumps faster(Circulatory System) to deliver more oxygen. As with any workout, my heart rate increases because I'm working much harder than I normally do. The skeletal muscles compress the veins near them which push the blood towards my heart. They contract and relax, driving extra blood to the heart which causes the heart rate to go up. Within this process, it means I'm putting more labor on my arm and leg muscles which pump more blood to my heart. So when working out the heart will get used to high-level performance, and these changes will minimize my resting heart rate and boost my heart rate recovery after I exercise.
- Lungs breathe faster(Respiratory System) to get more oxygen. As I exercise, the oxygen that reaches my muscles converts available glucose into ATP, providing my body with the energy it needs to complete my workout. Lungs provide energy, oxygen and eliminate carbon dioxide which is created when producing energy. When your muscles and your body start to work harder, you will use more oxygen and make more carbon dioxide.
- I'm out of my breath. Oh my god, look at the back of my jersey! It's all sweaty!
