b. three; atwo
c. four; atwo
d. four; athree
ANSWER: a C
The aheart ahas afour achambers: atwo aatria aand atwo aventricles. aThe aright aand aleft asides aof athe
aheartaare aseparated aby aan ainternal awall aof aconnective atissue acalled aa aseptum. aThe
ainteratrial aseptum aseparates athe aright aand aleft aatria. aThe ainterventricular aseptum
aseparates athe aright aand aleft aventricles. aThe asepta aseparate athe aheart ainto atwo afunctional
apumps. aThe aright aatrium aand aright aventricle amake aup aone apump. aThe aleft aatrium aand aleft
aventricle amake aup athe aother.
OBJ: a Identify aand adescribe athe achambers aof athe aheart aand athe avessels athat aenter aor aleave aeach.
7. Stimulation aof aalpha1 areceptors aresults ain .
a. increased aheart arate
b. peripheral avasoconstriction
c. constriction aof abronchial asmooth amuscle
d. increased aforce aof amyocardial acontraction
ANSWER: a B
Alpha1 areceptors aare afound ain athe aeyes, ablood avessels, abladder, aand amale areproductive
aorgans.aStimulation aof aalpha1 areceptor asites aresults ain aconstriction.
OBJ: a Compare aand acontrast athe aeffects aof asympathetic aand aparasympathetic astimulation aof athe aheart.
8. Which aside aof athe aheart ais aa alow-pressure asystem athat apumps avenous ablood ato athe alungs?
a. Left
b. Right
ANSWER: a B
The ajob aof athe aright aside aof athe aheart ais ato apump aunoxygenated ablood ato aand athrough athe
alungs ato athe aleft aside aof athe aheart. aThis ais acalled athe apulmonary acirculation. aThe aright aside aof
athe aheartais aa alow-pressure asystem.
