respiratory organ with its function
residual volume
is the amount of air remaining in the lungs after a forced expiration.
paranasal sinuses
reduces weight of skull, voice modulation
a hiccup is when
there is a spastic contraction of the diaphragm while the glottis is closed.
vital capacity
total lung capacity - the residual volume = vital capacity (the small space between big humps)
larynx
voice production
tidal volume
volume of air EXCHANGED during normal breathing (THE AMOUNT OF AIR YoU USE WHEN YOU BREATHE IN & OUT)
nasal cavity
warms, filters, and moistens air as it enters respiratory tract
pharynx
conveys air from nasal cavity to larynx
inspiratory CAPACITY
= to the inspiratory reserve volume + tidal volume.
inspiratory reserve volume
amount of air that can be inhaled AFTER a normal inspiration. (when swimming, you need to have a good inspiratory reserve volume because you need to have a good after breath)
bronchial tree
branching structures carrying air to alveoli.
lungs
comprised of airways and air sacs
trachea
conveys air from larynx to bronchial tree
nose
entry point for airflow during inspiration
