Pulmonary ventilation |
Movement of air from the atmosphere to the exchange surface at the alveoli of the lungs and back out. GASES ALWAYS MOVE FROM AREA OF HIGH TO LOW PRESSURE |
|
Inhalation |
For _____ vol. of lungs increases, decreasing pressure of air in the lungs below atmospheric pressure |
|
Exhalation |
For _____ the volume of lungs decreases. Pressure of gas in lungs will increase above atmospheric pressure and force the gases out of lungs. |
|
To prevent lungs from collapsing |
Why is intrapleural pressure always lower than intrapulmonic pressure? |
|
The lungs would collapse |
What would happen if intrapleural pressure was greater than intrapulmonic pressure? |
|
Pneumothorax |
What clinical condition causes the lungs to collapse? |
|
External respiration |
_____ _____ is the exchange of gases between the atmosphere and blood. It results in converting of deoxygenated blood to oxygenated blood. |
|
