x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# x#
ormed by portions of the right atrium and the left and right ventricles. However, because th
x# x# x# x# x# x# x# x# x# x# x# x# x# x# x#
e heart is tilted slightly toward the left in the chest, the right ventricle is the area of the hear
x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# 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 hea
x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# x#
rt are separated by an internal wall of connective tissue called a septum. The interatrial sept
x# x# x# x# x# x# x# x# x# x# x# x# x# x# x#
um separates the right and left atria. The interventricular septum separates the right and left
x# x# x# x# x# x# x# x# x# x# x# x# x# x#
ventricles. The septa separate the heart into two functional pumps. The right atrium and ri
x# x# x# x# x# x# x# x# x# x# x# x# x# x# x#
ght ventricle make up one pump. The left atrium and left ventricle make up the other.
x# x# x# x# x# x# x# x# x# x# x# x# x# x# x#

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. Sti
x# x# x# x# x# x# x# x# x# x# x# x# x# x#
mulation 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 lu
x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# x# x#
ngs to the left side of the heart. This is called the pulmonary circulation. The right side of th
