1. Stimulation x of x beta-adrenergic x receptor x sites x will x result x in x peripheral x vasoconstriction.
ANS: x F
Beta x receptor x sites x are x divided x into x beta1 x and x beta2. x Beta1 x receptors x are x found x in
x the x heart xand x kidneys. x Stimulation x of x beta1 x x receptor x sites x in x the x heart x results x in
x increased x heart xrate, x contractility, x and x ultimately x irritability x of x cardiac x cells.
x Stimulation x of x beta1 x receptor xsites x in x the x kidneys x results x in x the x release x of x renin
x into x the x blood. x Renin x promotes x the xproduction x of x angiotensin, x a x powerful
x vasoconstrictor. x Beta2 x receptor x sites x are x found x in xthe x arterioles x of x the x heart,
x lungs, x and x skeletal x muscle. x Stimulation x results x in x dilation.
Stimulation x of x beta2 x x receptor x sites x in x the x smooth x muscle x of x the x bronchi x results x in
x dilation.
OBJ: Compare x and x contrast x the x effects x of x sympathetic x and x parasympathetic x stimulation x of x the
x heart.
2. Blood x pressure x is x the x result x of x cardiac x output x and x peripheral x vascular x resistance.
ANS: x T
Blood xpressure xis xequal xto xcardiac xoutput xmultiplied xby xperipheral xvascular xresistance.
x Blood x pressure x is x the x force x exerted x by x the x circulating x blood x volume x on x the x walls
x of x the xarteries.
Peripheral x vascular x resistance x is xthe xresistance xto xthe xflow xof xblood xdetermined x by xblood
xvessel x diameter x and x the x tone x of x the x vascular x musculature.
OBJ: Identify x and x explain x the x components x of x blood x pressure x and x cardiac x output.

ANS: x D
The xfront x(anterior) xsurface xof xthe xheart xlies xbehind xthe xsternum xand xcostal xcartilages. xIt xis
xformed x by x portions x of x the x right x atrium x and x the xleft x and x right x ventricles. x However,
x because xthe xheart xis xtilted x slightly xtoward xthe xleft xin xthe xchest, x the xright xventricle xis xthe
xarea xof xthe xheart xthat x lies x most x directly x behind x the x sternum.
OBJ: x x Identify x the x surfaces x of x the x heart.
4. Blood x pressure x is x determined x by multiplied x by .
a. stroke x volume; x heart x rate
b. heart x rate; x cardiac x output
c. cardiac x output; x peripheral x vascular x resistance
d. stroke x volume; x peripheral x vascular x resistance
ANS: x C
Blood x pressure x is x equal x to x cardiac x output x multiplied x by x peripheral x vascular x resistance.
OBJ: x x Identify x and x explain x the x components x of x blood x pressure x and x cardiac x output.
5. The x right x atrium x receives x venous x blood x from x the x head, x neck, x and x thorax x via x the
x, xfrom xthe xremainder xof xthe xbody xvia xthe , xand xfrom xthe
xheart xvia xthe .
a. coronary x sinus; x superior x vena x cava; x inferior x vena x cava
b. superior x vena x cava; x coronary x sinus; x inferior x vena x cava
c. inferior x vena x cava; x superior x vena x cava; x coronary x sinus
d. superior x vena x cava; x inferior x vena x cava; x coronary x sinus
ANS: x D
The x right x atrium x receives x blood x low x in x oxygen x from x the x superior x vena x cava, x which
x carries xblood x from x the x head x and x upper x extremities; x the x inferior x vena x cava, x which
x carries x blood xfrom x the x lower x body; x and x the x coronary x sinus, x which x is x the x largest
x vein x that x drains x the xheart.
OBJ: Identify x and x describe x the x chambers x of x the x heart x and x the x vessels x that x enter x or x leave x each.
6. The x heart x is x divided x into chambers x but x functions x as x a -sided x pump.
a. two; x four
b. three; x two
c. four; x two

, The x heart x has x four x chambers: x two x atria x and x two x ventricles. x The x right x and x left x sides
x of x the xheart x are x separated x by x an x internal x wall x of x connective x tissue x called x a
x septum. x The xinteratrial x septum x separates xthe xright xand xleft xatria. xThe xinterventricular
x septum x separates xthe x right x and x left x ventricles. x The x septa x separate x the x heart x into x two
x functional x pumps. x The xright x atrium x and x right x ventricle x make x up x one x pump. x The
x left x atrium x and x left x ventricle xmake xup xthe xother.
OBJ: Identify x and x describe x the x chambers x of x the x heart x and x the x vessels x that x enter x or x leave x each.

c. constriction x of x bronchial x smooth x muscle
d. increased x force x of x myocardial x contraction
ANS: x B
Alpha1 x receptors x are xfound xin xthe xeyes, xblood x vessels, x bladder, x and xmale xreproductive
xorgans. x Stimulation x of x alpha1 x receptor x sites x results x in x constriction.

8. Which x side x of x the x heart x is x a x low-pressure x system x that x pumps x venous x blood x to x the
x lungs?
a. Left

ANS: x B
The x job x of x the x right x side x of x the x heart x is x to x pump x unoxygenated x blood x to x and x through
x the xlungs x to x the x left x side x of x the x heart. x This x is x called x the x pulmonary x circulation.
x The x right xside x of x the x heart x is x a xlow-pressure x system.

x to x the xsystemic xcirculation?
a. Left
b. Right
ANS: x A
The x left x side x of x the x heart x is x a x high-pressure x pump. x The x job x of x the x left x heart x is x to
x receive xoxygenated x blood x and x pump x it x out x to x the x rest x of x the x body. x This x is
x called x the x systemic xcirculation. x The x left x ventricle x is x a x high-pressure x chamber. x Its
x wall x is x much x thicker x than xthe x right x ventricle x (the x right x ventricle x is x 3 x to x 5 x mm
x thick; x the x left x ventricle x is x 13 x to x 15 xmm xthick). x This x is x because x the x left x ventricle
x must x overcome x a x lot x of x pressure x and xresistance x from x the x arteries x and x contract
x forcefully x in x order x to x pump x blood x out x to x the xbody.
OBJ: Identify x and x describe x the x chambers x of x the x heart x and x the x vessels x that x enter x or x leave x each.
