MULTIPLE F# CHOICE

1. The F # body’s mechanism
F # F # for conducting
F # air F #


in
F # F #and F # out of the F # F# F # lungs is known F # F #


as
F # F #which of
F # the F # F # following?
a. External respiration F# F#


b. Internal respiration F #


c. Spontaneous ventilation F #


d. Mechanical ventilation


ANS: C
The conduction
F # of air in andF # out of F # F # F # F # F #

F #the body
F # is known F # as ventilation. F # Since F # F# F #


F #the question
F # asks for the body’s
F # F # F # F #


mechanism,
F# this would
F # be spontaneous
F # F # F #

F #ventilation. External respiration
F # involves the F# F # F # F# F # F#


F#exchange of oxygen
F# F # (O2) F # and carbon
F# F# F# F# F# F# F#


F#dioxide (CO2)
F# between
F# the F# alveoli
F# and F# F# F# F# F# F# F#

F#the pulmonary
F# capillaries. Internal
F # respiration F # F #


F #occurs at the cellular
F # F # level and involves
F# F # F # F #


F #movement of oxygen
F # from the systemic
F # F # F # F#


F #blood into F # the cells. F # F #

2. Which of F # F # the F # following F # are F # involved F # in F # external
respiration?
F #


a. Red blood cells and body

F#


b. Scalenes and trapezius F # F #

muscles
F#


c. Alveoli and pulmonary

F #spontaneous breathing is depicted
F # F # F # F # by
which
F# of the

c.
d.


ANS: B
During spontaneous
F # breathing the F # F # F #intrapleural
F #pressure drops fromF# about -5 F # F # F # F # cm H2O F #

F #at end-expiration
F # to about F # F #


-10 cm
