ANS: D x@
The front (anterior) surface of the heart lies behind the sternum and costal cartilages. I
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
t is formed by portions of the right atrium and the left and right ventricles. However,
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
because the heart is tilted slightly toward the left in the chest, the right ventricle is the
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x
@area of the heart that lies most directly behind the sternum.

arries blood from the head and upper extremities; the inferior vena cava, which carries
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
blood from the lower body; and the coronary sinus, which is the largest vein that dr

a. two; four x@
b. three; two x@
c. four; two x@
d. four; three x@
ANS: C x@
The heart has four chambers: two atria and two ventricles. The right and left sides of t
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
he heart are separated by an internal wall of connective tissue called a septum. The int
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
eratrial septum separates the right and left atria. The interventricular septum separates t
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
he right and left ventricles. The septa separate the heart into two functional pumps. Th
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
e right atrium and right ventricle make up one pump. The left atrium and left ventricle
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
make up the other.
x@ x@ x@ x@
OBJ: x @ Identify and describe the chambers of the heart and the vessels that enter or leave each.

7. Stimulation of alpha1 receptors results in
x@ . x@ x@ x@ x@
a. increased heart rate x@ x@
b. peripheral vasoconstriction x@
c. constriction of bronchial smooth muscle x@ x@ x@ x@
d. increased force of myocardial contraction
x@ x@ x@ x@
ANS: B x@
Alpha1 receptors are found in the eyes, blood vessels, bladder, and male reproductive organ
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
s. Stimulation of alpha1 receptor sites results in constriction.
x@ x@ x@ x@ x@ x@ x@ x@
OBJ: x @ Compare and contrast the effects of sympathetic and parasympathetic stimulation of the hear
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@

8. Which side of the heart is a low-pressure system that pumps venous blood to the lungs?
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
a. Left
b. Right
ANS: B x@
The job of the right side of the heart is to pump unoxygenated blood to and through t
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
he lungs to the left side of the heart. This is called the pulmonary circulation. The right
x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@ x@
side of the heart is a low-pressure system.
