a. left atrium ZI
b. right atrium ZI
c. left ventricle ZI
d. right ventricle ZI
ANSWER: D Z I
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is forme
ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI
d by portions of the right atrium and the left and right ventricles. However, because the heart is ti
ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI
lted slightly toward the left in the chest, the right ventricle is the area of the heart thatlies most di

4. Blood pressure is determined by ZI multiplied by ZI ZI ZI ZI .
a. stroke volume; heart rate ZI ZI ZI
b. heart rate; cardiac output ZI ZI ZI
c. cardiac output; peripheral vascular resistance ZI ZI ZI ZI
d. stroke volume; peripheral vascular resistance ZI ZI ZI ZI

5. The right atrium receives venous blood from the head, neck, and thorax via the
ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI
,fromthe remainder of the body via the ZI IZ ZI ZI ZI ZI ZI ZI

c. inferior vena cava; superior vena cava; coronary sinus ZI ZI ZI ZI ZI ZI ZI
d. superior vena cava; inferior vena cava; coronary sinus ZI ZI ZI ZI ZI ZI ZI
ANSWER: D Z I
The right atrium receives blood low in oxygen from the superior vena cava, which carries bloo
ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI
d from the head and upper extremities; the inferior vena cava, which carries blood fromthe lo

6. The heart is divided into
ZI ZI ZI ZI chambers but functions as a ZI ZI ZI ZI -sided pump. ZI
a. two; four ZI
b. three; two ZI
c. four; two ZI
d. four; three ZI
ANSWER: C Z I
The heart has four chambers: two atria and two ventricles. The right and left sides of the heartar

arates the right and left atria. The interventricular septum separates the right and left ventricles
ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI ZI
. The septa separate the heart into two functional pumps. The right atrium and right ventricle m
