AEROSPACE PHYSIOLOGY FINAL
EXAM COMPLETE QUESTIONS WITH
100% VERIFIED ANSWERS
\.At MSL, the Earth's atmosphere consists of approximately 78% nitrogen, 21%
oxygen, and 1% other gases (by volume). These percentages are constant to an
altitude of _______________________. At and beyond that altitude, intense solar
radiation causes these molecules to split into their component atoms (NASA,
2013). - ANSWERS-270,000 feet msl
\.The percentage of oxygen in the atmosphere (when measured in mass or
volume) is generally the same at MSL and at FL 180. - ANSWERS-True
\.The "Physiological Efficient Zone" exists from - ANSWERS-MSL to 12,500 ft
\.The "Physiological Deficient Zone" exists from - ANSWERS-12,,500 feet MSL to
50,000 feet MSL
\.What is a healthy systolic/diastolic blood pressure for an adult human? -
ANSWERS-120/80
\.Hypertension is - ANSWERS-high blood pressure
,\.Hypoglycemia is associated with - ANSWERS-low blood sugar
\.The air in airliner cabins contains far less water moisture than typical air at sea
level. - ANSWERS-True
\.Why does the cabin in an airliner contain such a different amount of water vapor
than air at MSL? - ANSWERS-the air at cruise altitudes contains far less water
vapor than air at MSL
\.Which scientific Gas Law explains how the partial pressure of oxygen at higher
altitudes is insufficient for humans? - ANSWERS-Dalton's law
\.Which scientific Gas Law describes how chemicals in the liquid state, when
subjected to lower pressures, causes Decompression Sickness (DCS)? - ANSWERS-
Henrys law
\.If a human lives for long periods at high altitudes, their body adjusts to
accommodate. Which below is NOT a human body adaptation to life at high
altitude? - ANSWERS-More white blood cells
\.Which Gas Law explains the fundamental relationship between temperature and
pressure? If airplanes use oxygen tanks, the pressure of the tanks may drop as
temperature around them decreases. - ANSWERS-Charles Law
\.Within the human body, oxygen processing involves four steps. In order, these
steps are - ANSWERS-ventilation, respiration, transportation, utilization
, \.Regarding the respiration process, where does oxygen first get diffused in the
body? - ANSWERS-in the lungs, where it enters through alveoli
\.For humans, the respiration process brings in ____ and releases ____. -
ANSWERS-oxygen, carbon dioxide
\.The human body primarily regulates breathing rate by measuring - ANSWERS-
carbon dioxide levels at the carotid and aortic bodies
\.When exercising, breathing rate and heart rate increase due to - ANSWERS-
increase rate of oxygen use, and more demand for oyxgen
\.While resting, approximately how many breaths does a human take in one
minute? - ANSWERS-12-20 times
\.According to the American Heart Association, the threshold for high blood
pressure is - ANSWERS-130/80
\.FAA guidance to Aviation Medical Examiners states that the average blood
pressure while sitting shall not exceed - ANSWERS-155/95
\.What is a common blood-thinning medication to help with high blood pressure?
- ANSWERS-aspirin
