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
