1. Choose incorrect sentence: Cholecystokinin (CCK)
2. Hyperventilation results in the increase of arterial pO2 and reduction pCO2. What changes in diameter of cerebral vessels will be observed in these terms?
more pO2 / less pCO2
3. The value of Tiffeneau-Pinelli index (FEV1/FVC ratio) is predominantly determined by:
calculated ratio used in the diagnosis of obstructive and restrictive lung disease
Anatomical dead space is:
194.Resistance in airways leads to
Obstruction in airways causes that
Volume of air inhaled into the lungs depends on pressure changes in a pleural cave and on lung compliance, thus the changes of pressure in the airways result in volume changes of the chest cage.
11. a preterm infant has a surfactant deficiency. Without surfactant, many of the alveoli collapse at the end of each expiration, which lead to pulmonary failure. Which of the following changes is present in a preterm infant, compared with a normal infant?
Alveolar surface tension vs. pulmonary compliance
--> CHOOSE THE RIGHT PAIR
a. Decreased vs. increased
b. Increased vs. no change
c. Decreased vs. no change
d. Increased vs. decreased
d. increased alveolar surface tension and decreased pulmonary compliance
--> as type II alveolar cells produce surfactant which decreases surface tension to prevent collapse of alveoli
-> pulmonary compliance: is a measure of the lung's ability to stretch and expand (distensibility of elastic tissue)
