vocal folds
air pushed past vocal folds causes blank
vibration
pitch is controlled by changing tension of blank
cords

internal respiration
breathing works depending on the blank changes in the blank cavity
volume, thoracic
two phases of breathing
inspiration, expiration
volume changes lead to blank change in breathing
pressure
when pressure changes, gases flow to blank pressure
equalize
during inspiration, blank and blank muscles contract
external intercostal, diaphragm
on inspiration, this expands
thoracic cavity
on inspiration, pressure in the pleural cavity blank
decrease
on inspiration, air moves blank lungs to equalize pressure
into
a passive process where muscles relax and recoil shrinks thoracic cavity
expiration
during expiration, prussure blank in pleural cavity in lungs
increases
during this, internal intercostals, external obliques, and abdominal recti muscles contract
