| Question | Answer |
| What are the short term effects of exercise on the respiratory system? | • Increased breathing rate • Increased depth of breathing • Oxygen debt |
| What are the long term effects of exercise on the respiratory system? | • Strengthens intercostal muscles • Strengthens diaphragm • Increases the number of alveoli • Increases lung volume |
| What are the benefits of these long term effects? | • Respiratory system gets stronger • More air can be taken in and oxygen can be extracted more effectively to be delivered to working muscles • More effective removal of carbon dioxide |
| Define 'total lung capacity' | The total volume of air in your lungs after your biggest breath in |
| Define 'tidal volume' | The total amount of air breathed in and out in one cycle of normal breathing |
| Define 'vital capacity' | The maximum you can forcibly breathe in and out |
| What is oxygen debt? | The extra amount of oxygen required after anaerobic exercise to return to the amount normally needed when at rest (This doesn't happen during aerobic exercise) |
| How does smoking effect the respiratory system? | Carbon monoxide binds to the red blood cells so less oxygen can be carried around the body meaning less effective oxygen delivery to muscles |
