MULTIPLE CHOICE ||
1. The apex of the heart is formed by the
|| || || || || || || | .
a. tip of the left ventricle || || || |
b. tip of the right atrium || || || ||
c. right atrium and right ventricle || || || ||
d. left atrium and left ventricle | || || ||
ANS: A ||
The heart’s apex, or lower portion, is formed bythe tip of the left ventricle. The apex lies just
| || | | | | || | | | || | || || | | || || ||
above the diaphragm, between the fifth and sixth ribs, in the midclavicular line.
|| || || || || || || || || || || ||
OBJ: | | Identifythe surfaces of the heart. | || || || ||
2. The left atrium receives blood from the
| || || || || || .
a. pulmonary veins |
b. aorta
c. pulmonary arteries |
d. inferior vena cava | ||
ANS: A ||
The left atrium receives freshly oxygenated blood from the lungs via the right and left pulmonary
|| || || || | || || || | || | | | || ||
veins.
||
OBJ: | | Identifyand describe the chambers of the heart and the vessels that enter or leave each.
| | | || || || || || || || || | | || |
3. The anterior surface of the heart consists primarily of the
|| || || || || || || || | .
a. left atrium |
b. right atrium ||
c. left ventricle |
d. right ventricle |
ANS: D ||
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, because the
|| || || || || || || || || || || || || || || ||
heart is tilted slightly toward the left in the chest, the right ventricle is the area of the heart that
|| || || || || | || || || || || || || || || || || || || ||
lies most directly behind the sternum.
|| || || || ||
OBJ: | | Identifythe surfaces of the heart. | || || || ||
4. Blood pressure is determined by multiplied by
| || || || || .
a. stroke volume; heart rate | || ||
b. heart rate; cardiac output | | ||
c. cardiac output; peripheral vascular resistance | || || ||
d. stroke volume; peripheral vascular resistance | || || |
ANS: C ||
Blood pressure is equal to cardiac output multiplied byperipheral vascular resistance.
| || || || || || || || | || ||
, OBJ: | | Identifyand explain the components of blood pressure and cardiac output. | | || || || || | || | |
5. The right atrium receives venous blood from the head, neck, and thorax via the
|| || || || || || || || || || || || || ,from
| ||
the remainder of the body via the
|| , and from the heart via the || || || || || || || || || || || .
a. coronarysinus; superior vena cava; inferior vena cava | || || || || || ||
b. superior vena cava; coronarysinus; inferior vena cava | || || | || || ||
c. inferior vena cava; superior vena cava; coronary sinus | || || | || || |
d. superior vena cava; inferior vena cava; coronary sinus | | || || || || |
ANS: D ||
The right atrium receives blood low in oxygen from the superior vena cava, which carries
|| || || || || || || || || || || || || || ||
blood from the head and upper extremities; the inferior vena cava, which carries blood from the
|| || | || || | || || | | || || || || || ||
lower body; and the coronary sinus, which is the largest vein that drains the heart.
|| || || || || || || || || || || || || ||
OBJ: | | Identifyand describe the chambers of the heart and the vessels that enter or leave each. | | | || || || || || || || || | | || |
6. The heart is divided into
|| || || || chambers but functions as a | || || || -sided pump. |
a. two; four ||
b. three; two ||
c. four; two ||
d. four; three ||
ANS: C ||
The heart has four chambers: two atria and two ventricles. The right and left sides of the heart are
|| | || | || | || || | | || || || || || || || || ||
separated by an internal wall of connective tissue called a septum. The interatrial septum
|| || || || || || || || || || || || || ||
separates the right and left atria. The interventricular septum separates the right and left
|| || || || || || || || || || || || || ||
ventricles. The septa separate the heart into two functional pumps. The right atrium and right
|| || || || || || || || || || || || || || ||
ventricle make up one pump. The left atrium and left ventricle make up the other.
|| || || || || || || || || || || || || ||
OBJ: | | Identifyand describe the chambers of the heart and the vessels that enter or leave each. | | | || || || || || || || || | | || |
7. Stimulation of alpha1 receptors results in || || || | || .
a. increased heart rate | |
b. peripheral vasoconstriction ||
c. constriction of bronchial smooth muscle || | || ||
d. increased force of myocardial contraction || || | ||
ANS: B ||
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organs.
|| | | | | | | | | | | | | ||
Stimulation of alpha1 receptor sites results in constriction. || || || || || || ||
OBJ: | | Compareand contrast the effects of sympathetic and parasympathetic stimulation of the heart. | | | | || | | || | || | ||
8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
|| || || || || || | || || || || || || || ||
a. Left
b. Right
ANS: B ||
The job of the right side of the heart is to pump unoxygenated blood to and through the lungs
|| || || || || || || || || || || || || || || || || || ||
to the left side of the heart. This is called the pulmonary circulation. The right side of the heart is a
| | | | | | | || | | || || | || || | || | || || ||
low-pressure system. ||
