Place the respiratory structures below in the order that air would pass through them as it moves
from the outside to the inside of the body. - ANS
Fill in the blanks using the terms provided. Not all terms will be used - ANS The law of partial
pressure, also known as Dalton's law, states that the individual gases in the air contribute to the
total atmospheric pressure as a function of the percentage each gas contributes to the total volume.
If two gases have the same partial pressure, but gas A has a higher water solubility coefficient than
gas B, then gas A will diffuse at a faster rate.
Henry's law states that the amount of a gas that dissolves in water is a function of its partial pressure
and its solubility coefficient.
If the alveolar partial pressure of gas A is 110 mm Hg and the partial pressure of gas B is 135, then
gas B will diffuse into the blood at a faster rate.
If the P(CO2) in the tissues increases, then the P(CO2) in the systemic venous blood will increase.

Place the following in order from highest to lowest expected partial pressure oxygen levels. - ANS
Hyperpnea would result in ___________________________ within the blood. - ANS an increase in
Pressure (oxygen) and a decrease in Pressure (carbon dioxide)
Decreased Pressure (carbon dioxide) results in an increase in blood pH levels. Both of these
conditions result in a shift of the oxygen-hemoglobin dissociation curve to the
______________________. This shift _______________ hemoglobin's affinity for oxygen. - ANS left;
increases
Increased levels of 2,3 BPG occur in response to decreased blood pH levels. With all other variables
unchanged, an increased concentration of 2,3 BPG in the blood would _____________________. -
ANS result in a shift of the oxygen-hemoglobin dissociation curve to the right enhancing unloading
of oxygen at the tissues.
Using the graph provided, determine the correct oxygen partial pressure associated with the
classification of "high altitude." - ANS 112 mm Hg
The altitude of Kabul, Afghanistan is approximately 6000 feet. What is the approximate alveolar
oxygen partial pressure found here? - ANS 85 mm Hg
Under normal conditions, the alveolar oxygen partial pressure is ______________________ than the
atmospheric oxygen partial pressure. - ANS always lower
Within the Tibetan highlander population, genetic variation has been found to determine relative
oxygen-hemoglobin saturation levels. Individuals within this population may be homozygous for
either the low oxygen saturation gene or the high oxygen saturation gene. Individuals may also be
heterozygous, carrying one low and one high oxygen saturation gene. Based on this information,
individuals within the population carrying __________________________ alleles are expected to
demonstrated a physiological advantage for survival. - ANS homozygous high oxygen saturation
population
,No genetic differences were found among the Andean population in either oxygen-hemoglobin
saturation levels, nor hemoglobin concentrations. However, this group as a whole displayed higher
hemoglobin concentration levels than their lower altitude neighbors. The most accurate explanation
for this finding is that individuals constantly exposed to lower atmospheric partial pressures for
oxygen would have a physiologic response which would _______________________. - ANS increase
