BIO - respiratory Flashcards
respiratory system hels expel abdominal contents during defecation and childbirth
valsalva maneuver
loudness of a person’s voice depends on – with which air rushes across the vocal folds
force
– division of the autonomic nervous system controls the vasoconstriction of arterioles in response to temp changes
sympathetic
type I cells form the – of the alveolar wall
structure
type II cells secrete –
surfactant
Air moves out of the lungs when the pressure inside the lungs is – than the pressure in the atmosphere
greater
Expiration: recoil of elastic fibers that were stretched during inspiration and the inward pull of – due to the film of the alveolar fluid
surface tension
In a panting animal that breathes in and out rapidly, a large portion of new air comes into contact with the upper regions of the reparatory passages in order to decrease heat via
evaporation
What maintains the openness (patency) of the trachea?
C-shaped cartilage rings
intrapulmonary pressure is the pressure within the –
alveoli
surfactant helps to proven the alveoli from collapsing by disrupting the – of H2O thereby reducing the surface tension of alveolar fluid
cohesiveness
