maximal inspiration

13. Using the equation PV=constant; if the volume of the thoracic cavity increases (sizenof the thoracic cavity increases), the pressure inside the thoracic cavity will
A. increase
B. decrease
C. stay the same
D. increase, then will decrease after
14. When the pressure within the thoracic cavity increases compared to atmospheric
pressure, air will __ the lungs.
A. exit
B. enter
C. neither A nor B
D. cause Nitrogen concentration to increase
15. Using the equation PV=constant; if the volume of the thoracic cavity decreases (the
size of the thoracic cavity decreases), the pressure inside the thoracic cavity will
A. increase
B. decrease
C. stay the same
D. decrease then eventually increase
16. When the pressure within the thoracic cavity decreases as compared to the
atmospheric pressure, air will _ the lungs.
A. exit
B. enter
C. neither exit nor enter
D. cause Nitrogen gas to decrease
17. In order to inhale, the size of the thoracic cavity has to increase in order to decrease
the internal pressure compared to the atmospheric pressure. In order to
accomplish this task, which of the following must occur?
A. the diaphragm muscle and external intercostals contract
B. the diaphragm muscle and external intercostals relax
C. the diaphragm muscle contracts and the external intercostals relax.
D. the diaphragm muscle relax and the external intercostals contract.
18. Airway resistance is insignificant in relationship to gas flow because
A. the airway resistance is not related to the diameter of the conducting tubes in the respiratory system
B. the blood flow is very high in comparison to the viscosity of air
C. the airways branch more as they get smaller, resulting in a huge total cross-
sectional area
D. the gas flow stops in the medium-sized bronchioles and diffusion takes over,
therefore, airway resistance is no longer an issue.
