____ is when air is moving from the atmosphere into the lungs and from the lungs
into the atmosphere - ANSWER:ventilation
____ is gas exchange at the alveolar capillary membrane and at the tissue interface -
ANSWER:respiration
____ is the stretchability or the ease of the inflation of the lungs - ANSWER:lung
compliance
____ is defined as the change in volume by a change in pressure (V/P) -
ANSWER:lung compliance
____ is when there is a greater pressure required to get the same volume -
ANSWER:low compliance
____ is when there is a small decrease in the pressure which allow the lung to
collapse - ANSWER:high complicance
which is better: low or high compliance - ANSWER:neither; you want a lung with a
medium amount of complicance
what are the determinants of lung compliance - ANSWER:lung tissue, surface
tension, and surfactnat
if the lung tissue is thicker it is harder to open up so it is ____ compliant -
ANSWER:less
____ are like air filled sacs lined with water - ANSWER:alveoli
the pressure in the alveoli has to stretch the lung and over come the surface tension
of the ____ - ANSWER:water
since water has a very high surface tension, the lungs produce ____ -
ANSWER:surfactant
a lot of surface tension causes the lungs to have ____ compliance - ANSWER:low
____ decreases the surface tension in the alveoli and makes them easier to open -
ANSWER:surfactant
