alveoli
Gas exchange in the lungs occurs in the _____________-_____________ interface.

trachea & bronchi
What kind of epithelium tissue is in alveoli that does gas exchange?
simple squamous
What allows for the elastic recoil of the lung, which forces oxygen out?

Septal Cells
The movement of air into and out of the lungs is called ___________________ ____________________.
pulmonary ventilation
_______________ is an active process that requires contraction of the diaphragm.
Inspiration
____________ ___________ is a passive process that happens when the elastic fibers in the lungs cause the lungs to spontaneously recoil when the diaphragm relaxes.
Restful expiration
