Blood Composition
WBC (granular and agranular), RBC, Platelets, Plasma, Serum
Heart Anatomy
Be able to label the different parts of the heart
Blood Flow
Be able to trace the flow of blood through the heart
Cardiac Conduction System
Know the different components of the CCS and how the impulse flows
through the heart
SA Node, AV Node, AV Bundle, Purkinje Fibers
ECG
What happens during each wave of the electrocardiogram
Know the different abnormalities that we discussed in class

Trace the flow of electricity through the heart to conduct one
cardiac cycle.
Which part of the CCS is known as the hearts natural
pacemaker?
Stimulation from which nerve decreases the activity of the SA
Node and the AV node?
The AV bundle leads the depolarization into the ______ of the
heart along the purkinje fibers.
The individual cells in the heart do not act in unison.
True or False
Describe what occurs during the T Wave.
Describe what occurs during the P Wave.
Describe what occurs during the QRS Wave.
List and briefly describe two ECG abnormalities.
____1. Accumulation of plaque
buildup on walls of arteries
A.
Hypertension
B.
Coronary Artery Disease
____2. One or both cusps of mitral
valve stretches and bulges into left
atrium during ventricular
contraction.
C.
Myocardial Infarction
D.
Pericarditis
E.
Mitral Valve Prolapse
____3. Can cause the heart muscle
to die due to lack of oxygen.
____4. Caused by an obstructed
vessel in heart thrombus.
____5. Inflammation of pericardial
sac due to viral or bacterial
infection.
