Gcse PE Respiratory System

Structure:
1. Nose: Air Goes To Pharynx
  1. Pharynx: (Throat) Connects Nose To Larynx
    1. Larynx: Connects Pharynx To Trachea
      1. Trachea: Connects Larynx To Bronchi
        Bronchi: (The main tube that runs from the trachea to the bronchioles and tertiary bronchi)
        Bronchioles: The tertiary bronchus lead into the lungs
        Lung: The Main organ involved in respiration and ventilation
        Alveoli: Air sacs in lung and where gas exchange takes place
Function
1. Responsible For The Exchange Of Oxygen And Carbon Dioxide
2. Supplies Oxygen To The Blood
3. Gets Rid Of Carbon Dioxide And Other Waste Gasses
4. Inspiration And Expiration
5. Inside the cell, cellular respiration generates energy
Exchange Of Gasses
1. Internal
  1. The Alveoli in the lungs have a high level of oxygen
    1. Blood In Capillaries Have a low level of oxygen
2. External
  1. The blood in capillaries has a high level of carbon dioxide
    1. There is a low level of carbon dioxide in the alveoli of the lungs
Key Terms
1. Tidal Volume
  1. The amount of air breathed in or out with breath
2. Inspiratory Capacity
  1. The maximum amount of air you can breathe in ( after a normal breath out)
3. Expiratory Reserve Capacity
  1. After breathing out normally, this is the extra air you can breath out
4. Vital Capacity
  1. The maximum amount of air your could breath in or out in one breath
5. Residual Volume
  1. The amount of air left after you have breathe out as much as possible
Formulas
1. Anaerobic = glucose > lactic acid + energy released
  1. Aerobic = glucose + oxygen > carbon dioxide + water + energy
