  1. The effects of exercise on the respiratory system Hover over a hexagon for more information Breathing rate Gaseous exchange Tidal volume Effects Respiratory muscles Minute ventilation Vital capacity

  2. The effects of exercise on the respiratory system Breathing rate • Short Term – This increases due to an increase in the demand of oxygen by the exercising muscles. Breathing rate Gaseous exchange Tidal volume Effects Respiratory muscles Minute ventilation Vital capacity

  3. The effects of exercise on the respiratory system Tidal volume • Short Term – Tidal volume (the volume of air inspired or expired in one breath) increases due to an increased demand of oxygen by the exercising muscles. Breathing rate Gaseous exchange Tidal volume Effects Respiratory muscles Minute ventilation Vital capacity

  4. The effects of exercise on the respiratory system Minute ventilation • Short Term – Minute ventilation (the amount of air inspired or expired in one minute) increases due to an increased demand of oxygen by the working muscles. Breathing rate Gaseous exchange Tidal volume Effects Respiratory muscles Minute ventilation Vital capacity

  5. The effects of exercise on the respiratory system Vital capacity • Long Term – Vital capacity (the maximum amount of air that a person can expel from the lungs to their maximum extent) increases as the lungs become more efficient through training. Breathing rate Gaseous exchange Tidal volume Effects Respiratory muscles Minute ventilation Vital capacity

  6. The effects of exercise on the respiratory system Respiratory muscles • Long Term – The intercostal muscles and diaphragm increase in strength through training. This enables the lungs to expand more and therefore take in more oxygen. Breathing rate Gaseous exchange Tidal volume Effects Respiratory muscles Minute ventilation Vital capacity

  7. The effects of exercise on the respiratory system Gaseous exchange • Long Term – This increases as the capillary network surrounding the alveoli expands. This allows more oxygen and carbon dioxide to be exchanged. Breathing rate Gaseous exchange Tidal volume Effects Respiratory muscles Minute ventilation Vital capacity
