BIO SCI E109 MIDTERM 3 (FINAL)
EXAM REVIEW QUESTIONS WITH
CORRECT ANSWERS
\.Blood doping is the removal and storage of one's own erythrocytes. If this is
performed at the appropriate time before an athletic event, that athlete may have
an advantage over his or her competitors. What could be the problem with this
type of manipulation? - ANSWERS✔-increased blood viscosity
\.The associated figure shows how centrifuged blood separates into layers. The
process of centrifugation causes separation based on - ANSWERS✔-density
\.Which of the following is NOT true about blood cells? - ANSWERS✔-white blood
cells do not have a nucleus (when in circulation)
\.A common passageway shared by the respiratory and digestive systems is -
ANSWERS✔-pharynx
\.The partial pressure of O2 in the alveoli is lower than the partial pressure of O2
in the inhaled air because - ANSWERS✔-the inhaled air mixes with air remaining in
the lung
, \.You may refer to the spirogram provided below to answer this question. The
residual volume is - ANSWERS✔-the total lung capacity minus the vital capacity
\.There is usually 0 net diffusion of nitrogen from the alveoli into the pulmonary
capillaries. This is because - ANSWERS✔-there is the same partial pressure of
nitrogen in the blood and alveolar gas
\.Blocking afferent action potentials from the chemoreceptors in the carotid and
aortic bodies would interfere with the brain's ability to regulate breathing in
response to all except which of the following? - ANSWERS✔-changes in blood
pressure
\.what is maximized by ventilation-perfusion matching in the lungs? - ANSWERS✔-
the transfer of O2 from the lungs to the blood
\.While you are voluntarily holding your breath, and therefore there is no air
movement, what is happening - ANSWERS✔-the diaphragm is not receiving input
from the respiratory center
\.how does the ideal gas law PV=nRT help us understand how air is brought into
the lungs during inhalation? - ANSWERS✔-as volume increases, the pressure will
decrease
\.In one person (Sue) the PO2 in her alveoli was 100 mmHg, and the PO2 in her
resting cells was 40 mmHg. In a diff person (Fred), the PO2 in his alveoli was 80
mmHg, and the PO2 in his resting cells was 20 mmHg. How did the amount of O2
