Respiratory System (Disorders of the respiratory system (emphesyma…

- - - - adenocarcinoma
      - small cell carcinoma
      - squamous cell carcinoma
  - - - over secretion of thick mucus clogs respiratory system
  - - - 40 to 80 respirations/min
    - - 30 respirations/min
    - - 25 respirations/min
    - - 12 to 18 respirations/min
- - - - moistens air
      - traps incoming foreign particles
    - - increases surface area/air turbulance w/in the nasal cavity
  - - - lighten the skull
      - reasonance chambers for speech
      - frontal, sphenoid, ethmoid, maxillary bones
      - produce mucus
  - - - nasopharynx
        
        superior region behind nasal cavity
      - oropharynx
        
        middle region behind mouth
      - laryngopharnyx
        
        inferior region attached to larynx
  - - - beat continuously in opposite direction of incoming air
      - mucus loaded with dust/other debris away from lungs
- - - - residual volume + expiratory reserve volume
    - - inspiratory reserve volume + tidal volume + expiratory reserve volume
    - - tidal volume + inspiratory reserve volume
    - - sum of all volumes
  - - - air moved by one respiration, about 500mL, during normal breathing at rest
    - - additional air taken in during maximal inhalation
    - - additional air expired during forced exhalation
    - - amount of air left in alveoli after forced expiration, keeps them inflated
    - - air remaining in conducting zone; doesn't reach alveoli
  - - - temporary cessation of breathing
    - - painful or labored breathing
    - - normal, quiet breathing
    - - rapid breathing
  - - - several groups of neurons in medulla oblongata/pons (control rate/depth of breathing)
    - - increase carbon dioxide, decrease respiration; acts directly on medulla oblongata
      - carbon dioxide levels in blood is the main regulatory chemical for respiration
      - decrease oxygen levels, increase respiration
      - chemoreceptors in aorta/carotid artery
      - info sent to medulla oblongata
    - - talking
      - coughing
      - exercise
      - emotion
      - increased body temperature
- - - - moving air in and out of lungs
    - - oxygen carried as oxyhemoglobin in blood
    - - exchange of gases between blood and body cells
  - - - inspiration
        
        flow of air into lung (PL<PA)
      - expiration
        
        air leaving lung (PL>PA)
  - - - scalenes muscles, sternocleidomastoid, and pectoralis minor
- - - - tertiary bronchi
      - bronchioli
      - secondary bronchi
      - terminal bronchioli
      - primary bronchi
  - - - carbon dioxide enters alveoli
      - oxygen enters blood
  - - - branch from bronchioles
    - - out-pouching of alveolar duct
      - sites of gas exchange surrounded by capillaries
      - produce surfactant (coats alveolar surfaces) allows alveoli to expand
- - - - oxygen carried as oxyhemoglobin in blood
  - - - moving air in and out of lungs
- - - - paranasal sinuses
      - pharynx (throat)
      - nasal cavity
      - nose
    - - larynx
      - trachea
      - bronchial
      - tree
      - lungs
