Question

Please explain your answers and indicate whether each option is correct or incorrect. Thanks!

Select all of the following that are true regarding dynamic breathing conditions. During inspiration, intrapleural pressure is less than alveolar pressure AIncorrect B. Correct During expiration, intrapleural pressure becomes more negative than at rest During inspiratory flow, mouth pressure is greaterthan alveolar pressure Compliance is typically lower at TLC than at end of a normal tidal breath

Answer 1

• Correct

During inspiration the increased volume of alveoli decrease the intra alveolar pressure

• Incorrect

During expiration the intrapleural pressure becomes "less" negative than at rest because the inspired air is given out

• Correct

During inspiration The mouth pressure will be greater than alveolar pressure

• Correct

TLC compliance are typically lower
