n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7
ormed by portions of the right atrium and the left and right ventricles. However, because th
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7
e heart is tilted slightly toward the left in the chest, the right ventricle is the area of the hear
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7

The right atrium receives blood low in oxygen from the superior vena cava, which carries
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n
blood from the head and upper extremities; the inferior vena cava, which carries blood fro
7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7

a. two; four n7
b. three; two n7
c. four; two n7
d. four; three n7
ANS: C n7
The heart has four chambers: two atria and two ventricles. The right and left sides of the hea
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7
rt are separated by an internal wall of connective tissue called a septum. The interatrial sept
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7
um separates the right and left atria. The interventricular septum separates the right and left
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7
ventricles. The septa separate the heart into two functional pumps. The right atrium and ri
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7
ght ventricle make up one pump. The left atrium and left ventricle make up the other.

7. Stimulation of alpha1 receptors results in n7 n7 n7 n7 n7 .
a. increased heart rate n7 n7
b. peripheral vasoconstriction n7
c. constriction of bronchial smooth muscle n7 n7 n7 n7
d. increased force of myocardial contraction n7 n7 n7 n7
ANS: B n7
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organs. Sti
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7
mulation of alpha1 receptor sites results in constriction.

8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7
a. Left
b. Right
ANS: B n7
The job of the right side of the heart is to pump unoxygenated blood to and through the lu
n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7 n7
ngs to the left side of the heart. This is called the pulmonary circulation. The right side of th
