c. right ssatrium ssand ssright ssventricle
d. left ssatrium ssand ssleft ssventricle
ANSWER: s s A
The ssheart’s ssapex, ssor sslower ssportion, ssis ssformed ssby ssthe sstip ssof ssthe ssleft ssventricle. ssThe
ssapex sslies ssjusta
s bove ssthe ssdiaphragm, ssbetween ssthe ssfifth ssand sssixth ssribs, ssin ssthe
ssmidclavicular ssline.
OBJ: s s Identify ssthe sssurfaces ssof ssthe ssheart.
2. The ssleft ssatrium ssreceives ssblood ssfrom ssthe .
a. pulmonary ssveins
b. aorta
c. pulmonary ssarteries
d. inferior ssvena sscava
ANSWER: s s A
The ssleft ssatrium ssreceives ssfreshly ssoxygenated ssblood ssfrom ssthe sslungs ssvia ssthe ssright
ssand ssleftp
s ulmonary ssveins.
OBJ: s s Identify ssand ssdescribe ssthe sschambers ssof ssthe ssheart ssand ssthe ssvessels ssthat ssenter ssor ssleave
sseach.
3. The ssanterior sssurface ssof ssthe ssheart ssconsists ssprimarily ssof ssthe .
a. left ssatrium
b. right ssatrium
c. left ssventricle
d. right ssventricle
ANSWER: s s D
The ssfront ss(anterior) sssurface ssof ssthe ssheart sslies ssbehind ssthe sssternum ssand sscostal sscartilages.
ssIt ssis ssformed ssby ssportions ssof ssthe ssright ssatrium ss and ssthe ssleft ssand ssright ssventricles.
ssHowever, ssbecause ssthe ssheart ssis sstilted ssslightly sstoward ssthe ssleft ssin ssthe sschest, ssthe ssright
ssventricle ssis ssthe ssarea ssof ssthe ssheart ssthatslies ssmost ssdirectly ssbehind ssthe ss sternum.
OBJ: s s Identify ssthe sssurfaces ssof ssthe ssheart.
4. Blood sspressure ssis ssdetermined ssby multiplied ssby .
a. stroke ssvolume; ssheart ssrate
b. heart ssrate; sscardiac ssoutput
c. cardiac ssoutput; ssperipheral ssvascular ssresistance
d. stroke ssvolume; ssperipheral ssvascular ssresistance
ANSWER: s s C
Blood sspressure ssis ssequal ssto sscardiac ssoutput ssmultiplied ssby ssperipheral ssvascular ssresistance.
, OBJ: s s Identify ssand ssexplain ssthe sscomponents ssof ssblood sspressure ssand sscardiac ssoutput.
5. The ssright ssatrium ssreceives ssvenous ssblood ssfrom ssthe sshead, ssneck, ssand ssthorax ssvia ssthe ,
fromts he ssremainder ssof ssthe ssbody ssvia ssthe
ss , ssand ssfrom ssthe
ssheart ssvia ssthe .
a. coronary sssinus; sssuperior ssvena sscava; ssinferior ssvena sscava
b. superior ssvena sscava; sscoronary sssinus; ssinferior ssvena sscava
c. inferior ssvena sscava; sssuperior ssvena sscava; sscoronary sssinus
d. superior ssvena sscava; ssinferior ssvena sscava; sscoronary sssinus
ANSWER: s s D
The ssright ssatrium ssreceives ssblood sslow ssin ssoxygen ssfrom ssthe sssuperior ssvena sscava, sswhich
sscarries ssblood ssfrom ssthe sshead ssand ssupper ssextremities; ssthe ssinferior ssvena sscava, sswhich
sscarries ssblood ssfromsthe sslower ssbody; ssand ssthe sscoronary sssinus, sswhich ssis ssthe sslargest
ssvein ssthat ssdrains ssthe ssheart.
OBJ: s s Identify ssand ssdescribe ssthe sschambers ssof ssthe ssheart ssand ssthe ssvessels ssthat ssenter ssor ssleave
sseach.
6. The ssheart ssis ssdivided ssinto chambers ssbut ssfunctions ssas ssa -sided sspump.
a. two; ssfour
b. three; sstwo
c. four; sstwo
d. four; ssthree
ANSWER: s s C
The ssheart sshas ssfour sschambers: sstwo ssatria ssand sstwo ssventricles. ssThe ssright ssand ssleft sssides
ssof ssthe sshearta
s re ss separated ssby ssan ssinternal sswall ss of ssconnective sstissue sscalled ssa ssseptum.
ssThe ssinteratrial ssseptum ss separates ssthe ssright ssand ssleft ssatria. ssThe ssinterventricular ssseptum
ssseparates ssthe ssright ssand ssleft ssventricles. ssThe ss septa ssseparate ssthe ssheart ssinto sstwo
ssfunctional sspumps. ssThe ssright ss atrium ssand ssright ss ventricle ssmake ssup ssone sspump. ssThe ssleft
ssatrium ssand ssleft ssventricle ssmake ssup ssthe ssother.
OBJ: s s Identify ssand ssdescribe ssthe sschambers ssof ssthe ssheart ssand ssthe ssvessels ssthat ssenter ssor ssleave
sseach.
7. Stimulation ssof ssalpha1 ssreceptors ssresults ssin .
a. increased ssheart ssrate
b. peripheral ssvasoconstriction
c. constriction ssof ssbronchial sssmooth ssmuscle
d. increased ssforce ssof ssmyocardial sscontraction
ANSWER: s s B
Alpha1 ssreceptors ssare ssfound ssin ssthe sseyes, ssblood ssvessels, ssbladder, ssand ssmale ssreproductive
ssorgans.S
s timulation ssof ssalpha1 ssreceptor ss sites ssresults ssin ssconstriction.
OBJ: s s Compare ssand sscontrast ssthe sseffects ssof sssympathetic ssand ssparasympathetic ssstimulation ssof ssthe
