How do air molecules move in and out of the alveoli?

Passively, in response to pressure gradients.

What two natural forces must be overcome to open the lungs?

Elastic recoil and surface tension.

What is the primary function of the negative intrapleural pressure?

It sucks the lungs outward to keep them expanded.

Define lung compliance (CL).

The change in lung volume per unit change in transpulmonary pressure (ΔV/ΔP).

When is static compliance measured compared to dynamic compliance?

Static is measured at fixed volumes; dynamic is measured during normal rhythmic breathing.
