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


b. right atrium zx


c. left ventricle zx


d. right ventricle zx




ANSWER: D zx


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


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


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

a. stroke volume; heart rate zx zx zx


b. heart rate; cardiac output zx zx zx


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


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




ANSWER: C zx


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

6. The heart is divided intozx zx zx zx chambers but functions as a zx zx zx zx -sided pump. zx


a. two; four zx


b. three; two zx


c. four; two zx


d. four; three zx




ANSWER: C zx


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