Ventilation how much air we breathe in
How is ventilation controlled? moving air into & throughout the lungs into the
capillaries
controlled by:
- pons
- medulla oblongota
- "respiratory center of the brain"
Perfusion the flow of blood we need; provides oxygen to
the body
,How is perfusion controlled? blood flow to the alveoli; sit people upright if
they have trouble breathing; the lungs get the
most blood flow because of where they are
positioned in the body
controlled by:
- gravity
- body position
- exercise
- lung zones
Factors that affect perfusion and - fluid volume within lung
how the factors have their effect - fluid shifts
- interstitial edema
- alveolar edema
basically... if there is too much fluid
in/surrounding a space then blood will not be
able to perfuse there that well/at all
Diffusion - the air that's being sent to the alveoli
- gases are moving between the air spaces in
your lungs and blood stream constantly
think of a diffusor spreading essential oil vapor
into the air
UPPER structures of the airways - nasopharynx
- oropharynx
- laryngopharynx
NOL
, LOWER structures of the airways - larynx
- trachea
- bronchi
- bronchopulmonary segments
- bronchioles
LT B to the 3
What is the anatomical difference there are 2 lobes on the left lung & 3 lobes on
between the right and left lung? the right lung; you want to listen more to the
right side
What is the role of cilia in the - lines the trachea & bronchi
respiratory tract? - defense against microorganisms (they work to
trap microorganisms)
- cough reflex (after they have trapped things
you have to expel them)
- impaired function
coated in mucous, moist, traps things that come
in; if they function well, you will cough up any
allergens or debris that enter
