Respiratory system (p1) - Coggle Diagram

- - - - diaphragm flattens
      - external intercostals contract
      - thoracic volume
      - differences in pressure
      - ribs up and out
    - - same but more force
      - greater cavity
      - greater concentration gradient
      - air in faster
      - use of:
        
        percotrails minor
        
        scalenes
        
        sternocloidmastoid
  - - - diaphragm relax
      - ribs in and down
      - internal intercoastal
      - pressure increase
      - forced out
      - passive
    - - abdominals contract
      - internal intercoastal
      - air out faster
      - active
- - - - larynx
        
        trachea
        
        L/R bronchus
        L/R lung
        
        bronchioles
        
        terminal bronchiole

        at exercise use of:
        
        sternocleidomastoid
        
        pectoralis minor
  - - - increased rate and tidal volume
  - - - herring-bruer reflex

        quadratus lumborum
      - faster and deeper breathing out

        BR
        
        TV
        
        min vent
        
        oxy and co2 gradients - faster diffusion
        
        AVO2 diff
        
        body / blood temp
        
        blood less viscous increases o2 delivery
  - - - hypertrophy of respiratory muscles
      - increased vital capacity
      - utilise more % of alveoli
      - increased blood volume
        
        red blood cells
        
        HG
        
        oxy carrying capacity
      - increased content of myoglobin + mitochondria
      - capillarisation
        
        alveoli
        
        muscles
      - maximal AVO2 diff increase
- - - - oxygen intake and transport
      - lung vol & capacity
      - gas exchange avalibiltiy
      - o2 carrying capacity
        
        CO higher affinity
      - aerobic capacity
        
        fatigue quicker
- - - - hg partically saturated leaving muscles
  - - - oxygen attracted - helps diffusion
