ANSWER: A IIll



The heart’s apex, or lower portion, is formed by the tip of the left ventricle. The apex lies
IIll IIll IIll IIll IIll IIll IIll IIll Il IIll IIll IIll IIll IIll IIll IIll IIll



justabove the diaphragm, between the fifth and sixth ribs, in the midclavicular line.

a. left atrium IIll



b. right atrium IIll



c. left ventricle IIll



d. right ventricle IIll




ANSWER: D IIll



The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



formed by portions of the right atrium and the left and right ventricles. However, because
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



the heart is tilted slightly toward the left in the chest, the right ventricle is the area of the
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



heart thatlies most directly behind the sternum.

d. superior vena cava; inferior vena cava; coronary sinus IIll IIll IIll IIll IIll IIll IIll




ANSWER: D IIll



The right atrium receives blood low in oxygen from the superior vena cava, which
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



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



blood fromthe lower body; and the coronary sinus, which is the largest vein that drains
IIll IIll Il IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



the heart.

6. The heart is divided into
IIll IIll IIll IIll chambers but functions as a IIll IIll IIll IIll -sided pump. IIll



a. two; four IIll



b. three; two IIll



c. four; two IIll



d. four; three IIll




ANSWER: C IIll



The heart has four chambers: two atria and two ventricles. The right and left sides of the
IIll IIll IIll IIll IIll IIll IIll IIll IIll Il IIll IIll IIll IIll IIll IIll



heartare separated by an internal wall of connective tissue called a septum. The
IIll Il IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



interatrial septum separates the right and left atria. The interventricular septum
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



separates the right and left ventricles. The septa separate the heart into two functional
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



pumps. The right atrium and right ventricle make up one pump. The left atrium and left
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



ventricle make up the other.

7. Stimulation of alpha1 receptors results in IIll IIll IIll IIll IIll .
a. increased heart rate IIll IIll



b. peripheral vasoconstriction IIll



c. constriction of bronchial smooth muscle IIll IIll IIll IIll



d. increased force of myocardial contraction IIll IIll IIll IIll




ANSWER: B IIll



Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



organs.Stimulation of alpha1 receptor sites results in constriction.

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?
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



a. Left
b. Right
ANSWER: B IIll



The job of the right side of the heart is to pump unoxygenated blood to and through the
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



lungs to the left side of the heart. This is called the pulmonary circulation. The right side of
IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll IIll



the heartis a low-pressure system.
