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
area of the heart that lies most directly behind the sternum.

@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.
