Term
|
Definition
| Thin walled, air sacs that allow for gas diffusion. Each is surrounded by capillaries which allows for the gas exchange across the thin cell walls. |

Term
|
Definition
Parietal layer: lines wall of thoracic cavity.
Visceral layer: lines the wall of the lung.

Term
|
Definition
| Besides the diaphragm contracting and flattening out... the external intercostal muscles contract and the ribs and sternum elevate. This creates more room for air. |
|
|
Term
|
Definition
| Internal intercostals contract, ribs descend, and diaphram relaxes (moves more superiorly). |
