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.
