Respiratory membrane |
The alveolar and capillary walls form the respiratory membrane also known as the alveolar/capillary membrane, where gasintrapleural exchange occurs between the air on the alveolar side and blood on the capillary side |
|
Intrapleural pressure |
Pressure in the plural cavity surrounding the lungs it is always slightly negative in relation to atmospheric pressureintrap |
|
Intrapulmonary pressure |
Pressure within the lungs always equalizes the atmospheric pressure |
|
Tidal volume |
The degree of chest expansion during normal breathing is minimal requiring less energy expenditure. In adults approximately 500 mL of air is inspired and expired with each breath this is known as title volume |
|
Lung compliance |
The expense ability or stretchability of lung tissue, plays a significant role in the ease a ventilation |
|
Atelectasis |
Collapse of a portion of the lung |
|
Atelectasis |
Collapse of a portion of the lung |
|
Lung recoilp |
The continual tendency of the lungs to collapse away from the chest wall. Necessary for expiration |
|
Surfactant |
A lipo protein produced by specialized alveolar cells, acts like detergent, reducing the surface tension of Aveolar fluid |
|
Diffusion |
The movement of gases or other particles from an area of greater pressure or concentration to an area of low pressure or concentration |
|
Partial pressure |
The pressure exerted by each individual gas in the mixture according to its concentration in the mixture |
