the Heart
A.
Name the cavity where the heart is found.
Coverings of the
Heart
A.
Name the three coverings of the heart. Be able to identify them in a figure.
Wall of the Heart
A.
Name the three walls of the heart and their function. Be able to identify them
in a figure.
Heart Chambers and
Valves
A.
Identify the four chambers of the heart and from where they receive blood.
Review Table 15.2
Review Figure 15.6
Skeleton of the Heart
A. What constitutes the skeleton of the heart?
Path of Blood Through
the Heart
Review
Figure 15.10 (Know the flow of blood, what happens in the pulmonary circuit and
what happens in the systemic circuit)

Heart
A.
What arteries supply blood to the heart?

15.3:
Heart Actions
A.
Describe how atria and ventricles contract and relax.
Review Figure 15.16
Cardiac Cycle
A.
During a cardiac cycle, the pressure in the heart chambers rise and falls
B. Know the steps
in atrial systole and ventricular diastole.
C.
Know the steps in ventricular systole and atrial diastole.

A.
To what correspond the “lubb” and “dupp” sounds?
B. What is a
murmur?
Cardiac Muscle Fibers
A.
What is a functional syncytium?
Cardiac Conduction
System
A. What is the cardiac conduction system and what is
its function?
Review Figure 15.18 and
15.19
Electrocardiogram
A. What is an electrocardiogram?
B.
Describe the ECG waves.
Regulation of the
Cardiac Cycle
A.
What node controls the heart rate?
B. How sympathetic and parasympathetic fibers help
control the heart rate?
Review Figure 15.24
15.4:
Blood Vessels
A.
Describe the blood vessels of the
cardiovascular system (arteries, arterioles, capillaries, venules and veins) in
terms if their function.
