ANSWER: D n
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is formed
n n n n n n n n n n n n n n n n
by portions of the right atrium and the left and right ventricles. However, because the heart is
n n n n n n n n n n n n n n n n n
tilted slightly toward the left in the chest, the right ventricle is the area of the heart thatlies most

ANSWER: D n
The right atrium receives blood low in oxygen from the superior vena cava, which carries
n n n n n n n n n n n n n n
blood from the head and upper extremities; the inferior vena cava, which carries blood
n n n n n n n n n n n n n n
fromthe lower body; and the coronary sinus, which is the largest vein that drains the heart.

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

7. Stimulation of alpha1 receptors results in n n n n n .
a. increased heart rate n n
b. peripheral vasoconstriction n
c. constriction of bronchial smooth muscle n n n n
d. increased force of myocardial contraction n n n n
ANSWER: B n
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive
n n n n n n n n n n n n
organs.Stimulation of alpha1 receptor sites results in constriction.
n n n n n n n n n
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?
n n n n n n n n n n n n n n n
a. Left
b. Right
ANSWER: B n
The job of the right side of the heart is to pump unoxygenated blood to and through the lungs to
n n n n n n n n n n n n n n n n n n n
the left side of the heart. This is called the pulmonary circulation. The right side of the heartis a
