ctions
Which of the following is wrong:
A- At start of inspiration, the Intrapleural pressure is -2.5 mmHg.
B- The change in lung volume / unit change in pressure is called compliance.
C- The surfactant is secreted by type II alveolar epithelial cells.
D- The primary cause of emphysema is increased elastase enz. Activity
e- The normal transmural pressure of the lung = -4 mmHg
Other
Please Specify:
The lung compliance is decreased in all of the following Except:
A- Lung fibrosis.
B- Lung stiffness.
C- Old age.
D- Pulmonary congestion & pulmonary edema,
All of the following statements are true Except:
A- Glottis is open during inspiration & expiration.
B- Low surface tension in alveoli due to surfactant increases compliance.
C- Low surface tension in alveoli due to surfactant decreases compliance.
D- Surfactant helps to keep the alveoli dry.
The anterior abdominal wall muscles are expiratory muscles because:
A- They pull the ribs downward & inward decreasing transverse diameter.
B- They act during resting.
C- They push the diaphragm upwards.
D- All of the above.
During Valsalva maneuver, which of the following is correct:
A- Intrapulmonary pr +100, Intrathoracic pr +50 & glottis is open.
B- Intrapulmonary pr +100, Intrathoracic pr -50 & glottis is closed.
C- Intrapulmonary pr +100, Intrathoracic pr +50 & glottis is closed
D- Air can flow into lung but can`t be expelled out.
Concerning work of breathing, all of the following is true except:
A- It`s performed normally during inspiratory phase only.
B- It`s expended in stretching the elastic tissues of chest wall & lungs & to move the inelastic tissues & moving air in the respiratory passages.
C- The elastic work required to inflate lungs alone is equal to the work required to inflate the whole respiratory system.
D- It`s increased in emphysema, asthma & pulmonary congestion.
About Surfactant, all of the following is true except:
A- It`s active ingredient is phospholipid in nature.
B- It`s effectiveness is concentration dependent.
C- It`s effectiveness is more in expiration than inspiration.
D- It`s secreted from alveolar Pneumocytes type II under effect of parathyroid hormone.
