1. The apex of the heart is formed bythe
ht ht ht ht ht ht ht ht .
a. tip of the left ventricleht ht ht 1a



b. tip of the right atrium ht ht ht ht



c. right atrium and right ventricle ht ht ht ht



d. left atrium and left ventricle ht ht ht ht




ANSWER: A h t



Theheart’s apex, or lower portion, is formed bythe tip ofthe left ventricle. The apex lies just ab ove t

c. pulmonary arteries ht



d. inferior vena cava ht ht




ANSWER: A h t



The left atrium receives freshlyoxygenated blood from the lungs via the right and left pulmona ry v

3. The anterior surface of the heart consists primarily of the
ht ht ht ht ht ht ht ht ht .
a. left atrium ht



b. right atrium ht



c. left ventricle ht



d. right ventricle ht




ANSWER: D h t



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



by portions of the right atrium and the left and right ventricles. However, because the heart is tilt
ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht



ed slightlytoward the left in the chest, the right ventricle is the area of the heart that lies m ost directl

4. Blood pressure is determined by
ht multiplied by ht ht ht ht .
a. strokevolume; heart rate ht ht ht



b. heart rate; cardiac output ht ht ht



c. cardiac output; peripheral vascular resistance ht ht ht ht



d. strokevolume; peripheral vascular resistance ht ht ht ht




ANSWER: C h t



Blood pressure is equal to cardiac output multiplied byperipheral vascular resistance.

5. The right atrium receives venous blood from the head, neck, and thorax via the

d. superior vena cava; inferior vena cava; coronarysinus ht ht ht ht ht ht ht




ANSWER: D h t



The right atrium receives blood low in oxygen from the superior vena cava, which carries bl oo

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



a. two; four ht



b. three; two ht



c. four; two ht



d. four; three ht




ANSWER: C h t



The heart has four chambers: two atria and two ventricles. The right and left sides of the heart ar e sep

arated by an internal wall of connective tissue called a septum. The interatrial septum sep arates t

he right and left atria. The interventricular septum separates the right and left ventricles
ht ht ht ht ht ht ht ht ht ht ht ht ht



. The septa separate the heart into two functional pumps. The right atrium and right ventricle m
ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht



ake up one pump. The left atrium and left ventricle make up the other.

7. Stimulation of alpha1 receptors results in ht ht ht ht ht .
a. increased heart rate 1a ht



b. peripheral vasoconstriction ht



c. constriction of bronchial smooth muscle ht ht ht ht



d. increased force ofmyocardial contraction 1a ht ht ht




ANSWER: B h t



Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organs. Stimu lati

8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
1a ht ht ht ht ht ht ht ht ht ht 1a ht ht ht



a. Left
b. Right
ANSWER: B h t



The job of the right side of the heart is to pump unoxygenated blood to and through the lungs t o th
ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht ht



e left side of the heart. This is called the pulmonary circulation. The right side of the heart is a low-
