Respiratory System (DIsorders (Lung cancer (1/3 of all cancer…

- - - - Temporary cessation of breathing
    - - Painful or labored breathing
    - - Normal,quiet breathing
    - - Rapid breathing
  - - - Residual volume+expiratory reserve volume
    - - Inspiratory reserve volume+tidal volume+expiratory reserve volume
    - - Tidal volume+inspiratory reserve volume
    - - Sum of all volumes
- - - - Cavities within bones
      - Lighten the skull/speech/produce mucus
    - - Muscular passage from nasal cavity to larynx
    - - Moistens air/traps incoming foreign particles
      - Olfactory receptors located in mucosa on superior surfacce
    - - Air enters nose through external nares (nostrils)
    - - superior larynx, flap of cartilage that opens to allow air to pass and closes when swallowing food or drink
  - - - Connects larynx with bronchi
      - Windpipe that connects upper respiratory tract to lower respiratory tract
    - - Formed by the division of trachea
      - Bronchi subdivide into smaller and smaller branches
      - Bronchioles
        
        Further division of tertiary bronchi, less cartilage and more smooth muscle
      - Alveoli
        
        at end of terminal bronchioles, site of gas exchange
    - - Occupy most of thoracic cavity
      - Each lung is divided into lobes by fissures (2 left,3 right)
    - - voice box, cartilage
- - - - Wider,shorter,and straighter than the left, due to the presence of the heart
        
        Right lung
        
        Bigger then the left lung/
        found in pleural cavity, from clavicle to diphragm
    - - Main two branches of of trachea; branches to right and left lungs, they branch 3 times
        
        Left lung
        
        10% shorter then the right lung/
        found in pleural cavity, from clavicle to diphragm
