How are relaxation pressures from passive recoil and/or passive
generated? rebound forces of respiratory tissues. Ex:
inflated balloon returning back to resting
state by passively deflating.
Passive ways to change lung -Natural recoil of muscle, cartilage,
volumes and pressures (3) ligaments, and lung tissues
-Surface tension of fluid lining alveoli
-Downward pull of gravity
, Central idea for respiratory -Air is placed under pressure and
activity during speech (4) released in a regulated manner
-System provides "driving forces"
necessary for sound generation
-Active forces work to: displace
structures, create pressure behind valves,
and generate pressurized airflows
through constrictions in the upper airway.
-Bring in a lot of air very quickly through
the mouth
Respiratory activity during -Very regular and periodic and requires a
quiet breathing (2) combination of both active and passive
forces. (Active inhale, passive exhale)
-Smaller amounts of air come in through
the nose
What happens during quiet -Lung pressure decreases to less than
inhalation according to Boyle's atmospheric pressure.
law? (3) -As the P alv decreases, air is forced into
the respiratory system through either the
mouth or nose.
-Air will continue to enter the respiratory
system as long as P alv < P atm
