MULTIPLE CHOICE uy




1. The apex of the heart is formed by the
uy uy uy uy uy uy uy uy .
a. tip of the left ventricle uy uy uy uy



b. tip of the right atrium uy uy uy uy



c. right atrium and right ventricle uy uy uy uy



d. left atrium and left ventricle uy uy uy uy




ANSWER: A uy



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



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

2. The left atrium receives blood from the
uy uy uy uy uy uy .
a. pulmonary veins uy



b. aorta
c. pulmonary arteries uy



d. inferior vena cava uy uy




ANSWER: A uy



The left atrium receives freshly oxygenated blood from the lungs via the right and le

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



b. right atrium uy



c. left ventricle uy



d. right ventricle uy




ANSWER: D uy



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



rmed by portions of the right atrium and the left and right ventricles. However, because the
uy uy uy uy uy uy uy uy uy uy uy uy uy uy uy uy



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



hatlies most directly behind the sternum.

4. Blood pressure is determined by uy multiplied by uy uy uy uy .
a. stroke volume; heart rate uy uy uy



b. heart rate; cardiac output uy uy uy



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



d. stroke volume; peripheral vascular resistance uy uy uy uy




ANSWER: C uy



Blood pressure is equal to cardiac output multiplied by peripheral vascular resistance.

a. coronary sinus; superior vena cava; inferior vena cava uy uy uy uy uy uy uy



b. superior vena cava; coronary sinus; inferior vena cava uy uy uy uy uy uy uy



c. inferior vena cava; superior vena cava; coronary sinus
uy uy uy uy uy uy uy



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




ANSWER: D uy



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



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



omthe lower body; and the coronary sinus, which is the largest vein that drains the heart.

6. The heart is divided intouy uy uy uy chambers but functions as a uy uy uy uy -sided pump. uy



a. two; four uy



b. three; two uy



c. four; two uy



d. four; three uy




ANSWER: C uy



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



artare separated by an internal wall of connective tissue called a septum. The interatrial se
yu uy uy uy uy uy uy uy uy uy uy uy uy uy uy



ptum separates the right and left atria. The interventricular septum separates the right and
uy uy uy uy uy uy uy uy uy uy uy uy uy u



left ventricles. The septa separate the heart into two functional pumps. The right atrium an
y uy uy uy uy uy uy uy uy uy uy uy uy uy uy



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

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



b. peripheral vasoconstriction uy



c. constriction of bronchial smooth muscle uy uy uy uy



d. increased force of myocardial contraction uy uy uy uy

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



a. Left
b. Right
ANSWER: B uy



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



gs to the left side of the heart. This is called the pulmonary circulation. The right side of the h
uy uy uy uy uy uy uy uy uy uy uy uy uy uy uy uy uy uy uy



eartis a low-pressure system.
