Answer 2

Answer:

While the pleural membranes, and the pleural fluid, allow the lungs to move smoothly within the cavity.

The process of breathing, or respiration, is divided into two distinct phases. The first phase is called inspiration, or inhaling. When the lungs inhale, the diaphragm contracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside. As a result, air rushes in and fills the lungs.

The second phase is called expiration, or exhaling.
