1. The apex of the heart is formed by the

b. tip of the right atrium
gg g g g g g g


c. right atrium and right ventricle

d. left atrium and left ventricle
gg gg g g g g




ANS: g g A
The heart’s apex, or lower portion, is formed by the tip of the left ventricle.
gg gg gg gg gg gg gg gg gg gg gg gg gg gg


The apex lies just above the diaphragm, between the fifth and sixth ribs,

in the midclavicular line.

OBJ: Identify the surfaces of the heart.

a. pulmonary veins gg


b. aorta

d. inferior vena cava gg g g




ANS: g g A
The left atrium receives freshly oxygenated blood from the lungs via the right and
gg gg gg g g gg gg g g gg gg gg gg gg gg


left pulmonary veins.

OBJ: Identify and describe the chambers of the heart and the vessels that enter or

leave each.

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


b. right atrium gg


c. left ventricle gg


d. right ventricle gg




ANS: g g D
The front (anterior) surface of the heart lies behind the sternum and costal
g g g g g g g g g g g g g g g g g g g g g g g g


cartilages. It is formed by portions of the right atrium and the left and
g g g g g g gg g g g g g g g g g g g g g g g g g g g g


right ventricles. However, because the heart is tilted slightly toward the
g g g g g g g g g g g g g g g g g g gg g g


left in the chest, the right ventricle is the area of the heart that lies
g g g g g g g g g g g g g g g g g g gg g g g g g g g g g g


most directly behind the sternum.
