- Unit 1.2.3
- Respiratory System
- Includes: Lungs, Trachea, Bonchi, Diaphragm.
- Function: O2 in, CO2 out.
- Regular exercise increase lung capacity, enables more O2 to be taken in with each breath.
- Measurements
- Help estimate efficiency.
- Breathing rate: Number of breaths in a minute.
- Tidal volume: Amount of air inspired and expired with each normal breath at rest/during exercise.
- Vital capacity: Amount of air that can be expired after inspiring as deeply as possible.
- Immediate effects of exercise
- BR increases, Depth of breathing increases, Oxygen debt.
- Oxygen Debt
- Vigorous exercise makes body need more O2 than it can get.
- The extra O2 consumed during the recovery from a period of strenuous exercise, compared with the amount that would be consumed normally.
- Effects of smoking
- Damages alveoli makes them less efficient reduces O2 intake/CO2 removal, Short of breath, Lung diease/cancer.
- Long term benefits of exercise
- Increased lung capacity, Increased vital capacity, Increased tidal volume, More efficient.
- Respiratory System
