alveolus
one of the many small, grape-like sacs that are attached to the alveolar ducts.
alveolar sac
cluster of many individual alveoli that are responsible for gas exchange.
Boyles law formula
P1V1 = P2V2
boyles law
pressure and volume and inversely related
inspiration
inhalation of air into the lungs.
expiration
exhalation of lungs
