1. The apex of the heart is formed by the
x x x x x x x x .
a. tip of the left ventricle
x x x x
b. tip of the right atriumx x x x
c. right atrium and right ventricle x x x x
d. left atrium and left ventricle x x x x
ANS: A x
The heart’s apex, or lower portion, is formed by the tip of the left ventricle. The apex lies just abov
x x x x x x x x x x x x x x x x x x x
e the diaphragm, between the fifth and sixth ribs, in the midclavicular line.
x x x x x x x x x x x x
OBJ: Identify the surfaces of the heart.
x x x x x x
2. The left atrium receives blood from the
x x x x x x .
a. pulmonary veins x
b. aorta
c. pulmonary arteries x
d. inferior vena cava x x
ANS: A x
The left atrium receives freshly oxygenated blood from the lungs via the right and left pulmonary
x x x x x x x x x x x x x x x x
veins.
OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.
x x x x x x x x x x x x x x x x
3. The anterior surface of the heart consists primarily of the
x x x x x x x x x .
a. left atrium x
b. right atrium x
c. left ventricle x
d. right ventricle x
ANS: D x
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is formed
x x x x x x x x x x x x x x x x x
by portions of the right atrium and the left and right ventricles. However, because the heart is tilte
x x x x x x x x x x x x x x x x x
d slightly toward the left in the chest, the right ventricle is the area of the heart that lies most direct
x x x x x x x x x x x x x x x x x x x x
ly behind the sternum.
x x x
OBJ: Identify the surfaces of the heart.
x x x x x x
4. Blood pressure is determined by
x multiplied by x x x x .
a. stroke volume; heart rate x x x
b. heart rate; cardiac output x x x
c. cardiac output; peripheral vascular resistance x x x x
d. stroke volume; peripheral vascular resistance x x x x
ANS: C x
Blood pressure is equal to cardiac output multiplied by peripheral vascular resistance.

5. The right atrium receives venous blood from the head, neck, and thorax via the

x x x x x x x
c. inferior vena cava; superior vena cava; coronary sinus
x x x x x x x
d. superior vena cava; inferior vena cava; coronary sinus
x x x x x x x
ANS: D x
The right atrium receives blood low in oxygen from the superior vena cava, which carries blood
x x x x x x x x x x x x x x x
from the head and upper extremities; the inferior vena cava, which carries blood from the lower
x x x x x x x x x x x x x x x x x
body; and the coronary sinus, which is the largest vein that drains the heart.
x x x x x x x x x x x x x
OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.
x x x x x x x x x x x x x x x x
6. The heart is divided into
x x x x chambers but functions as a x x x x -sided pump. x
a. two; four x
b. three; two x
c. four; two x
d. four; three x
ANS: C x
The heart has four chambers: two atria and two ventricles. The right and left sides of the heart are s
x x x x x x x x x x x x x x x x x x x
eparated by an internal wall of connective tissue called a septum. The interatrial septum separates
x x x x x x x x x x x x x x
xthe right and left atria. The interventricular septum separates the right and left ventricles. The sep
x x x x x x x x x x x x x x x
ta separate the heart into two functional pumps. The right atrium and right ventricle make up one
x x x x x x x x x x x x x x x x x
pump. The left atrium and left ventricle make up the other.
x x x x x x x x x x
OBJ: Identify and describe the chambers of the heart and the vessels that enter or leave each.
x x x x x x x x x x x x x x x x
7. Stimulation of alpha1 receptors results in x x x x x .
a. increased heart rate x x
b. peripheral vasoconstriction x
c. constriction of bronchial smooth muscle x x x x
d. increased force of myocardial contraction x x x x
ANS: B x
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organs. Stimula
x x x x x x x x x x x x x x
tion of alpha1 receptor sites results in constriction.
x x x x x x x
OBJ: Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.
x x x x x x x x x x x x x
8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
x x x x x x x x x x x x x x x
a. Left
b. Right
ANS: B x
The job of the right side of the heart is to pump unoxygenated blood to and through the lungs to th
x x x x x x x x x x x x x x x x x x x x
e left side of the heart. This is called the pulmonary circulation. The right side of the heart is a low-
x x x x x x x x x x x x x x x x x x x x
pressure system. x
