Chapter 22-Respiratory System
Which of the following is not a function of the nasal conchae and mucosa? Filter the air entering the nasal cavity. Extract heat and moisture from the air leaving the nasal cavity. Heat and moisten the air entering the nasal cavity. Destroy pathogens entering the nasopharynx
Which of the following respiratory structures is more commonly known as the "throat"?
=throat
The _________________ is also known as the "guardian of the airways".
=epiglottis
________, the difference between the intrapulmonary and intrapleural pressures, prevents the lungs from collapsing.
=transpulmonary pressure
Quiet inspiration is ____________, and quiet expiration is ______________.
=an active process; a passive process …show more content…
=vital capacity
Complete the following statement using the choices below. Air moves out of the lungs when the pressure inside the lungs is
=greater than the pressure in the atmosphere.
Unlike inspiration, expiration is a passive act because no muscular contractions are involved. Expiration, however, depends on two factors. Which of the choices below lists those two factors?
=the recoil of elastic fibers that were stretched during inspiration and the inward pull of surface tension due to the film of alveolar fluid
Intrapulmonary pressure is the ________.
=pressure within the alveoli of the lungs
__________ has a greater partial pressure in the pulmonary capillaries than in the alveoli, so it diffuses into the __________.
=CO2; alveoli
Which gas law explains why there is as much CO2 exchanged between the alveoli and blood as there is O2 exchanged, despite the fact that the partial pressure difference is so much smaller for CO2?
=Henry’s
