ANSWER: s s A
The heart’s apex, or lower portion, is formed bythe tip of the left ventricle. The apex lies
ss ss ss ss ss ss ss ss s ss ss ss ss ss ss ss ss
just above the diaphragm, between the fifth and sixth ribs, in the midclavicular line.

ANSWER: s s D
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
formed by portions of the right atrium and the left and right ventricles. However, because
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss

ANSWER: s s D
The right atrium receives blood low in oxygen from the superior vena cava, which carries
ss ss ss ss ss ss ss ss ss ss ss ss ss ss
blood from the head and upper extremities; the inferior vena cava, which carries blood
ss ss ss ss ss ss ss ss ss ss ss ss ss ss

the heart.

6. The heart is divided into
ss ss ss ss chambers but functions as a ss ss ss ss -sided pump. ss
a. two; four ss
b. three; two ss
c. four; two ss
d. four; three ss
ANSWER: s s C
The heart has four chambers: two atria and two ventricles. The right and left sides of the
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
heartare separated by an internal wall of connective tissue called a septum. The interatrial
ss ss ss ss ss ss ss ss ss ss ss ss ss ss
septum separates the right and left atria. The interventricular septum separates the right
ss ss ss ss ss ss ss ss ss ss ss ss ss
s and left ventricles. The septa separate the heart into two functional pumps. The right
s ss ss ss ss ss ss ss ss ss ss ss ss ss
s atrium and right ventricle make up one pump. The left atrium and left ventricle make up
s ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
the other.

7. Stimulation of alpha1 receptors results in ss ss ss ss ss .
a. increased heart rate ss ss
b. peripheral vasoconstriction ss
c. constriction of bronchial smooth muscle ss ss ss ss
d. increased force of myocardial contraction ss ss ss ss
ANSWER: s s B
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive
ss ss ss ss ss ss ss ss ss ss ss ss
organs.Stimulation of alpha1 receptor sites results in constriction.
ss ss ss ss ss ss ss ss
OBJ: s s Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.
ss ss ss ss ss ss ss ss ss ss ss ss
8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
a. Left
b. Right
ANSWER: s s B
The job of the right side of the heart is to pump unoxygenated blood to and through the
ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
slungs to the left side of the heart. This is called the pulmonary circulation. The right side
s ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss ss
of the heartis a low-pressure system.
