AEROSPACE PHYSIOLOGY EXAM WITH
COMPLETE QUESTIONS AND 100%
CORRECT ANSWERS { GRADED A+}
What is the approximate percentage of oxygen, nitrogen and other gases at 18,000
feet MSL? - ✔✔21 percent oxygen, 78 percent nitrogen and 1 percent other gases.
Which of the following is the best description of atmospheric pressure and its
cause? - ✔✔The combined weight of all the atmospheric gases which is caused by
gravity pulling the gas molecules earthward and thermal and solar radiation
expanding the gases outward toward space.
What are the common units used to measure atmospheric pressure? - ✔✔Inches
of mercury (inHg)
Millimeters of mercury (mmHg)
Pounds per square inch (psi)
, Which of the following represents the notation for the partial pressure of gases? -
✔✔PO2 partial pressure of oxygen, PCO2 partial pressure of carbon dioxide, PN2
partial pressure of nitrogen.
PO2 increases and the percentage of oxygen decreases as the altitude increases. -
✔✔False
What is the temperature lapse rate up to approximately 35,000 feet? - ✔✔About 2
°C per 1,000 feet
The human body is adapted to which physiological division of the atmosphere? -
✔✔Physiological zone
Gas law that explains why the temperature increases in a cylinder that is being
pressurized - ✔✔Charle's Law
Gas law that explains why a balloon expands as it ascends and also why a volume
of air expands when trapped in a body cavity when the pressure is reduced around
it. - ✔✔Boyle's Law
Gas law that explains how oxygen moves out of the lungs into the bloodstream. -
✔✔Grahm's Law
