Briefly describe the difference between atmospheric pressure,
intrapulmonary pressure, and
intrapleural pressure. Which of these is always negative in a
healthy individual during normal breathing? What happens if
intrapleural pressure becomes equal to atmospheric pressure?
Briefly differentiate between atmospheric pressure,
intrapulmonary pressure, and intrapleural pressure. Which of these
is always negative in a healthy individual during normal breathing?
What happens if intrapleural pressure becomes equal to atmospheric
pressure? The contraction of the diaphragm and the external
intercostal muscles begins inspiration. Explain exactly what
happens, in terms of volume and pressure changes in the lungs, when
these muscles contract. What is the functional significance of the
pleural fluid during inspiration?
