The primary biological purpose of respiration is to
to provide the means of gas exchange between an organism and its environment
- respiratory function (physiology) changes as we exercise, age, suffer
Goals of respiration
oxygenation of blood and elimination of carbon dioxide, waste products
Nonbiological purposes of respiration are to
provide a source for phonation and to provide the energy source for speech.
Inspiration
- quiet inspiration: only need diaphragm
- active (forced) inspiration: supports speech production
Expiration
- passive expiration: system is restored to a resting position after respiration, driven by forces of
elasticity and gravity
- active expiration: speech sounds, muscular effort enhances acts of expiration, abdomen is
compressed, muscles reduce size of thorax, rib cage pulled down, air pulled out of lungs

capable of quiet respiration as well as forced inspiration & expiration
- expiration may be passive (driven by elasticity and gravity)
- also use muscles that reduce the size of the thorax by compressing the abdomen or pulling the
rib cage down, and this will force air out of the lungs beyond that which is expired in passive
expiration.
The quantity of air processed...
through respiration is dictated primarily by bodily needs
Spirometer
rate of air flow in respiration, volume, lung capacities
Manometer
forced produced when blowing in a tube, pressure
How much you can inhale and exhale is...
relative to your quiet breathing volume
Process of respiration and gas exchange
breathing requires gas be exchanged on an ongoing basis to sustain life
stages = ventilation, diffusion, perfusion
