MULTIPLE CHOICE mm




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



b. tip of the right atrium
mm mm mm mm



c. right atrium and right ventricle
mm mm mm mm



d. left atrium and left ventricle
mm mm mm mm




ANSWER: A mm



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



lies justabove the diaphragm, between the fifth and sixth ribs, in the midclavicular
mm mm m mm mm mm mm mm mm mm mm mm mm mm



line.

OBJ: Identify the surfaces of the heart.

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



b. aorta
c. pulmonary arteries mm



d. inferior vena cava mm mm




ANSWER: A mm



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



and leftpulmonary veins.

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



b. right atrium mm



c. left ventricle mm



d. right ventricle mm




ANSWER: D mm



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

is formed by portions of the right atrium and the left and right ventricles. However,
mm mm mm mm mm mm mm mm mm mm mm mm mm mm mm



because the heart is tilted slightly toward the left in the chest, the right ventricle is the

area of the heart thatlies most directly behind the sternum.

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



b. heart rate; cardiac output
mm mm mm



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



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




ANSWER: C mm
