Question 1
pts
A premature baby and is having difficulty producing surfactant. Explain what problems
may occur and why.
Breathing difficulty (respiratory distress) is likely to occur. Without surfactant, the alveoli will
start sticking together and collapsing during exhalation because the surfactant normally
covers the luminal surface that prevents the alveoli from sticking together. This also causes
less of a gas exchange.
, Question 7
pts
The bronchioles are surrounded by capillaries for gas exchange.
False
Question 12
pts
Charles's law states that gas volume is:
A. A. Indirectly proportional to its temperature
B. B. Directly proportional to its pressure
C. C. Directly proportional to its temperature
D. D. Indirectly proportional to its pressure
1. Boyle’s Law – The pressure of a given quantity of gas is inversely proportional to its
volume
2. Charles’s Law – The volume of a given quantity of gas is directly proportional to its
temperature.
3. Dalton’s Law – The total pressure of a gas mixture is equal to the sum of the partial
pressures(pp) of the individual gases
Question 12
pts
