Where mmprecisely mmis mmthe mmheart mmlocated? mm- mmcorrect mmanswer-The mmheart mmsits mmin mmthe
mmmediastinum mm(the mmspace mmbetween mmthe mmlungs), mmjust mma mmlittle mmto mmthe mmleft mmof mmthe mmcenter
mmin mmmost mmpeople mm(2/3 mmof mmthe mmheart mmis mmleft mmof mmcenter, mmwhile mm1/3 mmis mmright).
How mmmany mmchambers mmdoes mmthe mmheart mmhave? mmHow mmmany mmon mmthe mmright? mmHow mmmany mmon
mmthe mmleft? mmWhat mmare mmthe mmtwo mmlarger mmchambers mmcalled? mmWhat mmare mmthe mmtwo mmsmaller
mmchambers mmcalled? mm- mmcorrect mmanswer-The mmheart mmhas mm4 mmchambers mm(2 mmon mmeach mmside). mmThe
mmlarger mmchambers mmare mmcalled mmventricles, mmand mmthe mmsmaller mmones mmare mmcalled mmthe mmatrium.
What mmis mmthe mmname mmof mmthe mmwall mmwhich mmseparates mmthe mmright mmside mmof mmthe mmheart mmfrom mmthe
mmleft? mm- mmcorrect mmanswer-This mmwall mmis mmcalled mmthe mmseptum
Describe mmthe mmjob mmof mmeach mmatrium. mmDescribe mmthe mmjob mmof mmeach mmventricle. mm- mmcorrect
mmanswer-The mmAtria mmreceive mmblood mmfrom mmeither mmthe mmbody mm(RA) mmor mmthe mmlungs mm(LA). mmThe
mmventricles mmreceive mmblood mmfrom mmthe mmAtria, mmand mmthen mmpump mmit mmfrom mmthe mmheart mmto mmthe
mmbody mm(LV) mmor mmthe mmlungs mm(RV).
What mmis mmthe mmpulmonary mmcirculatory mmpathway? mmWhat mmis mmthe mmsystemic mmcirculatory mmpathway?
mmdescribe mmthe mmoxygenation mmof mmthe mmblood mmand mmall mmparts mmof mmeach mmpathway. mm- mmcorrect
mmanswer-The mmpulmonary mmcirculatory mmpathway mmdescribes mmthe mmflow mmof mmdeoxygenated mmblood
mmfrom mmthe mmright mmventricle mmto mmthe mmlungs mmvia mmthe mmpulmonary mmarteries. mmOxygenated mmblood
mmthen mmreturns mmto mmthe mmleft mmatrium mmfrom mmthe mmlungs mmby mmfor mmpulmonary mmveins. mmThe
mmsystemic mmcirculatory mmpathway mmdescribes mmthe mmflow mmof mmoxygenated mmblood mmfrom mmthe mmleft
mmventricle mmto mmthe mmbody mmvia mmthe mmaorta. mmDeoxygenated mmblood mmthen mmreturns mmto mmthe mmright
mmatrium mmfrom mmthe mmbody mmvia mmthe mmIVC mmand mmSVC mmand mmcoronary mmsinus.
How mmmany mmgreat mmvessels mmare mmthere? mmWhat mmare mmtheir mmnames? mmWhere mmdo mmthey mmbegin,
mmand mmwhere mmdo mmthey mmend? mm- mmcorrect mmanswer-there mmare mmfive mmgreat mmvessels. mm1: mmAorta
mmfrom mmthe mmleft mmventricle mmto mmthe mmbody. mm2: mmPulmonary mmarteries mmfrom mmthe mmright mmventricle
mmto mmthe mmlungs. mm3: mmSVC mmfrom mmthe mmupper mmbody mmto mmthe mmright mmatrium. mm4: mmIVC mmfrom mmlower
mmbody mmto mmright mmatrium. mm5: mmPulmonary mmveins mmfrom mmlungs mmto mmthe mmleft mmatrium.
, How mmmany mmvessels mmbring mmblood mmback mmto mmthe mmright mmatrium? mmWhat mmare mmtheir mmnames? mm-
mmcorrect mmanswer-There mmare mmthree mmvessels mmwhich mmbring mmblood mmback mmto mmthe mmright mmatrium.
mmThey mmare mmthe mminferior mmvena mmcava mm(IVC) mmfrom mmthe mmabdomen mmand mmlower mmextremities, mmthe
mmsuperior mmvena mmcava mm(SVC) mmfrom mmthe mmhead mmand mmupper mmextremities, mmand mmthe mmcoronary
mmsinus mm(CS) mmfrom mmthe mmheart mmwalls mmthemselves.
How mmmany mmvessels mmbring mmblood mmback mmto mmthe mmleft mmatrium? mmWhat mmare mmtheir mmnames? mm-
mmcorrect mmanswer-There mmare mmfour mmvessels mmwhich mmbring mmblood mmback mmto mmthe mmleft mmatrium.
mmThey mmare mmall mmpulmonary mmveins, mmupper mmand mmlower mmfrom mmeach mmlung.
Define mmthe mmfollowing mmfour mmterms, mmand mmgive mmthe mmnormal mmrange mmfor mmeach: mmstroke mmvolume:
ejection mmfraction:
heart mmrate:
cardiac mmoutput: mm- mmcorrect mmanswer-Stroke mmvolume mmis mmthe mmamount mmof mmblood mmejected mmfrom mma
mmchamber mmof mmthe mmheart mmper mmbeat mm(70 mmto mm100 mmml).
Ejection mmfraction mmthe mmpercentage mmof mmblood mmejected mmfrom mma mmchamber mmof mmthe mmheart mmper
mmbeat mm(55 mmto mm75%). mm
Heart mmrate mmthe mmnumber mmof mmtimes mmper mmminute mmthe mmheart mmbeats mm(60 mmto mm100 mmBPM).
Cardiac mmoutput mmthe mmamount mmof mmblood mmejected mmfrom mma mmchamber mmof mmthe mmheart mmper
mmminute mm(4-8 mmliters/min)
Give mmthe mmformula mmused mmto mmfind mmcardiac mmoutput mm- mmcorrect mmanswer-CO=SV×HR
Define mmthe mmterms mmbasal mmand mmapical mmregarding mmthe mmheart. mm- mmcorrect mmanswer-Basal mmmeans
mmtoward mmthe mmbase mmof mmthe mmheart, mmwhich mmis mmformed mmby mmthe mmtop mmof mmthe mmAtria. mmTherefore
mmthe mmbasal mmusually mmmeans mmSuperior mmand mmmedial mmin mmthe mmbody. mmApical mmmeans mmtowards mmthe
mmapex mmof mmthe mmheart, mmwhich mmis mmformed mmby mmthe mmtip mmof mmthe mmventricles. mmTherefore mmapical
mmusually mmmeans mminferior mmand mmlateral mmin mmthe mmbody.
Describe mmthe mmshape mmof mmthe mmright mmventricle mmand mmthe mmleft mmventricle. mmWhich mmventricle mmhas
mmthicker mmwalls? mmWhy? mm- mmcorrect mmanswer-the mmright mmventricle mmis mmtriangular mmshaped, mmwhile
mmthe mmleft mmventricle mmis mmmore mmbullet-shaped mm(elliptical). mmThe mmleft mmventricle mmhas mmmuch mmthicker
