Respiratory System - Coggle Diagram

- - - - thin, slippery membrane that covers the surface of the lungs and dips into the areas separating the different lobes of the lungs.
      - inner layer of the pleural membrane
      - covers the lungs, blood vessels, nerves and bronchi
    - - outer membrane that lines the inner chest wall and diaphragm (muscles separating the chest and abdominal cavities)
      - layer of pleura associated with the walls of the pleural cavity
      - lines internal aspect of the thoric wall, the thoracic surface of the diaphragm and separates the pleural cavity from the mediastinum
      - the partial pleura is divided into four parts.
        
        The cervical parts of parietal pleura
        -the costal part of partial pleura
        
        the mediastinal part of parietal pleura
        
        the diaphragmatic part of the parietal pleura
- - - - inspiration = inhaling, the act of drawing air into the lungs
      - an active process
      - the diaphragm moves down by contracting and becoming flat.
      - inspired air is an oxygennitrogen mix.
      - oxygen is taken into the lungs
      - the rib cage moves forward and outward by the action of intercostal muscles.
      - the size of the chest cavity decreases
    - - expiration = exhalation the act of releasing air from the lungs through the nose or mouth
      - a passive process
      - the diaphragm moves up by relaxing and becoming a domeshaped
      - expired air is a carbon dioxide-nitrogen mix
      - air moves out of the lungs
      - carbon dioxide is removed from the lungs
      - the rib cage moves downward and inward by the action of intercostal muscles
      - the size of the chest cavity decreases
- - - - about 500 mL
      - is the amount of air inspired during normal, relaxed breathing
    - - -about 3,100 mL
      - is the additional air that can be forcibly inhaled after the inspiration of a normal tidal volume.
    - - about 1,200 mL
      - is the additional air that can be forcibly exhaled after the expiration of a normal tidal volume
    - - about 1,200 mL
      - is the volume of air still remaining in the lungs after the expiratory reserve volume is exhaled
  - - - about 6,000 mL
      - is the maximum amount of air that can fill the lungs
      - TLC = TV + IRV + ERV + RV
    - - about 4,800 mL
      - is the maximum amount of air that can fill the lungs
      - TLC = TV + IRV + ERV + RV
    - - about 3,600 mL
      - is the maximum amount of air that can be inspired
      - IC = TV + IRV
    - - about 2,400 mL
      - is the amount of air remaining in the lungs after a normal expiration
      - FRC = RV + ERV
