- I'm gonna do exercise!
- When we do exercise, the mitochondria in cells uses up the oxygen and glucose in our body to make energy through cellular respiration. And we need more energy than usual so the heart pumps more blood to carry more oxygen and glucose to the cells that does respiration to make energy.
- We need oxygen and glucose to make energy!
- I should send more blood to lungs and body so that the cells can make more energy out of oxygen and glucose!
- Because our cells need more oxygen than usual, the respiratory system allows/consumes more oxygen than regular days. And the pumped blood from heart takes it to the cells.
- I'm now letting more oxygen to come in so that the body can make energy!
- I'm carrying oxygen from alveoli and transporting it to cells!
- Capillary
- The cellular respiration starts with blood picking up oxygen from the lungs. The hemoglobin transports the oxygen through our body. When we breathe in, the alveoli is filled with oxygen. Those oxygens are diffused into the capillaries because it has very thin outside layer. The diffused oxygen is carried by the hemoglobin.
- Oxygen Alveoli
- How glucose is also transported through the bloods. The nutrients from food are digested from the intestines and are absorbed to the blood. Then, it is transported to cells those that need it. Another way to get glucose is through the fats which are stored in your body.
- Move them to cells!
- Carbon Dioxide
- As an outcome of cellular respiration, except for energy, the Co2 comes out as the exhale. Water is also created and we do our business in toilet to segregate them. With the energy generated, the muscle cells can make energy for exercise. On regular days, the generated energy is stored in ATP. We use ATP to move our bodies and it's also used in cells. For cells, an example of usage of ATP is active transport, which doesn't occur naturally. The body use ATP for moving muscles. This is how cellular respiration starts, ends, and how energy generated from it is used by our body.
