xventricle xmake xup xthe xother.
OBJ: x Identify xand xdescribe xthe xchambers xof xthe xheart xand xthe xvessels xthat xenter xor xleave xeach.
7. Stimulation xof xalpha1 xreceptors xresults xin .
a. increased xheart xrate
b. peripheral xvasoconstriction
c. constriction xof xbronchial xsmooth xmuscle
d. increased xforce xof xmyocardial xcontraction
ANSWER: x B
Alpha1 xreceptors xare xfound xin xthe xeyes, xblood xvessels, xbladder, xand xmale xreproductive
xorgans.x
Stimulation xof xalpha1 xreceptor xsites xresults xin xconstriction.
OBJ: x Compare xand xcontrast xthe xeffects xof xsympathetic xand xparasympathetic xstimulation xof xthe
xheart.
8. Which xside xof xthe xheart xis xa xlow-pressure xsystem xthat xpumps xvenous xblood xto xthe xlungs?
a. Left
b. Right
ANSWER: x B
The xjob xof xthe xright xside xof xthe xheart xis xto xpump xunoxygenated xblood xto xand xthrough xthe
xlungs xto xthe xleft xside xof xthe xheart. xThis xis xcalled xthe xpulmonary x circulation. xThe xright
xside xof xthe xheartxis xa xlow-pressure xsystem.
