Transcript
 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
 Heart Disorders
 Study the jigsaw fact sheet; specifically know what each disorder is
It seems like a lot, but you’ve got this!!

 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.
