Human Respiratory system
Your nose warms and moistens air
Your cilia (throat) pushes foreign substances and mucous up, until the epiglottis, so I can
be swallowed
Components of the lower respiratory tract
Extra mucous in your system is uncomfortable, that’s how you feel when you’re sick
Conductive zone vs. Respiratory zone
Conductive zone (no gas exchange)
oMouth/nose Trachea larnyx Bronchi  Bronchioles  Humidifies, warms and filters
air
Respiratory System (gas exchange)
oBronchioles Alveoli
Gas Exchange between the blood and alveoli
Cold air can damage alveoli in the lungs
Cutting open and setting out your alveoli has the surface area of a tennis court

Lung function test
A machine called a spirometer which measure the volume of air that you breath in and
out
oTidal volume - is the amount of air you’re inhaling and exhaling per normal breath
oTotal lung capacity – everything that is in your lungs (all the air)
oVital lung capacity – taking a maximal inhalation and maximum exhalation
oResidual volume – once giving you maximum exhalation, there is still some air left in
your lungs so your lungs don’t fully deflate then lean over and stick together which
will cause more air to unstick. If somehow you get all the air out, you will die
oFunctional residual volume – the air that’s left over after a normal breath
Lung Numbers
Tidal volume – 500 ml for the average adult male and female (remember that they are
the same)
Total lung capacity – (6000 ml – average adult males) (4200 ml – average adult females)
Minute ventilation – how much you are ventilating in a given minute
How to figure it out:
Minute Ventilation (rest) = Breathing Freq (breath/min) * Tidal Volume (L)
= 12-15 (breath/min) * 0.5 (L)
= 6.0 – 7.5 L/min
*Average adult takes 12-15 breaths per minute and should have 6-7.5 L/minute of minute
