ANSWER: D YU
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. I
YU YU YU YU YU YU YU YU YU YU YU YU YU YU
t is formed by portions of the right atrium and the left and right ventricles. However,
YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU Y

YU YU YU YU YU YU YU YU YU YU YU YU YU
s blood from the lower body; and the coronary sinus, which is the largest vein that
YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU
drains the heart. YU YU

6. The heart is divided into
YU YU YU YU chambers but functions as a YU YU YU YU -sided pump. YU
a. two; four YU
b. three; two YU
c. four; two YU
d. four; three YU
ANSWER: C YU
The heart has four chambers: two atria and two ventricles. The right and left sides of t
YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU
he heart are separated by an internal wall of connective tissue called a septum. The in
YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU
teratrial septum separates the right and left atria. The interventricular septum separates
YU YU YU YU YU YU YU YU YU YU YU YU
the right and left ventricles. The septa separate the heart into two functional pumps. T
YU YU YU YU YU YU YU YU YU YU YU YU YU YU
he right atrium and right ventricle make up one pump. The left atrium and left ventric
YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU
le make up the other.

YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU
7. Stimulation of alpha1 receptors results in
YU . YU YU YU YU
a. increased heart rate YU YU
b. peripheral vasoconstriction YU
c. constriction of bronchial smooth muscle YU YU YU YU
d. increased force of myocardial contraction
YU YU YU YU
ANSWER: B YU
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organ
YU YU YU YU YU YU YU YU YU YU YU YU YU
s. Stimulation of alpha1 receptor sites results in constriction.
YU YU YU YU YU YU YU YU
OBJ: Compare and contrast the effects of sympathetic and parasympathetic stimulation of the heart.
YU YU YU YU YU YU YU YU YU YU YU YU YU
8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU
a. Left
b. Right
ANSWER: B YU
The job of the right side of the heart is to pump unoxygenated blood to and through
YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU
the lungs to the left side of the heart. This is called the pulmonary circulation. The rig
YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU YU
