b. tip of the right atriumsx sx sx sx


c. right atrium and right ventricle sx sx sx sx


d. left atrium and left ventricle

ANSWER: A sx


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

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

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


b. right atrium sx


c. left ventricle sx


d. right ventricle sx




ANSWER: D sx


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


med by portions of the right atrium and the left and right ventricles. However, because the h

a. stroke volume; heart rate sx sx sx


b. heart rate; cardiac output sx sx sx


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


d. stroke volume; peripheral vascular resistance

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




ANSWER: D sx


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


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


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

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


a. two; four sx


b. three; two sx


c. four; two sx


d. four; three sx




ANSWER: C sx


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

m separates the right and left atria. The interventricular septum separates the right and left
sx sx sx sx sx sx sx sx sx sx sx sx sx sx sx


ventricles. The septa separate the heart into two functional pumps. The right atrium and rig

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

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


a. Left
b. Right
ANSWER: B sx


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


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