The front (anterior) surface of the heart lies behind the sternum and costal cartilages. It is formed
c c c c c c c c c c c c c c c c
by portions of the right atrium and the left and right ventricles. However, because the heart is

c c c c chambers but functions as a c c c c -sided pump. c
a. two; four c
b. three; two c
c. four; two c
d. four; three c
ANSWER: C c
The heart has four chambers: two atria and two ventricles.The right and left sides of the heartare
c c c c c c c c c c c c c c c c c c
separated by an internal wall of connective tissue called a septum. The interatrial septum
c c c c c c c c c c c c c c
separates the right and left atria. The interventricular septum separates the right and left
c c c c c c c c c c c c c c
ventricles. The septa separate the heart into two functional pumps. The right atrium and right
c c c c c c c c c c c c c c c
ventricle make up one pump. The left atrium and left ventricle make up the other.

7. Stimulation of alpha1 receptors results in c c c c c .
a. increased heart rate c c
b. peripheral vasoconstriction c
c. constriction of bronchial smooth muscle c c c c
d. increased force of myocardial contraction c c c c
ANSWER: B c
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive
c c c c c c c c c c c c
organs.Stimulation of alpha1 receptor sites results in constriction.
c c c c c c c c c
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?
c c c c c c c c c c c c c c c
a. Left
b. Right
ANSWER: B c
The job of the right side of the heart is to pump unoxygenated blood to and through the lungs to
c c c c c c c c c c c c c c c c c c c
the left side of the heart. This is called the pulmonary circulation. The right side of the heartis a
