ANS: A gz
The heart’s apex, or lower portion, is formed by the tip of the left ventricle. The apex lies just ab

3. The anterior surface of the heart consists primarily of the
gz gz gz gz gz gz gz gz gz .
a. left atrium gz
b. right atrium gz

ANS: D gz
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is form
gz gz gz gz gz gz gz gz gz gz gz gz gz gz gz gz
ed by portions of the right atrium and the left and right ventricles. However, because the heart
gz gz gz gz gz gz gz gz gz gz gz gz gz gz gz gz gz
is tilted slightly toward the left in the chest, the right ventricle is the area of the heart that lies m

od from the head and upper extremities; the inferior vena cava, which carries blood from the l

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

7. Stimulation of alpha1 receptors results in gz gz gz gz gz .
a. increased heart rate gz gz
b. peripheral vasoconstriction gz
c. constriction of bronchial smooth muscle gz gz gz gz
d. increased force of myocardial contraction gz gz gz gz
ANS: B gz
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organs. Stimu
gz gz gz gz gz gz gz gz gz gz gz gz gz gz
lation of alpha1 receptor sites results in constriction.
gz gz gz gz gz gz gz
OBJ: Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.

8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
gz gz gz gz gz gz gz gz gz gz gz gz gz gz gz
a. Left
b. Right
ANS: B gz
The job of the right side of the heart is to pump unoxygenated blood to and through the lungs t
