Review for Cardiac Exam
K ANATOMY REVIEW
Test Monday 3/30/15 – K ANATOMY
• Heart Anatomy – Chambers, structures and flow of blood, Coronary artery
function
Remember this diagram
from your JOURNAL!
Layers of the heart:
1. Pericardium (sac) – Epicardium,
Parietal Pericardium
2. Myocardium – Muscle
3. Endocardium – epithelial
lining
Key Vocabulary:
• Systole, Diastole, Bradycardia, Tachycardia, Angina Pectoris,
Electrocardiogram, P-Wave, QRS-Complex/Wave, T-Wave,
Vasoconstriction, Vasodilation
• Artery, Vein, Capillary, Arteriole, Venule, Lumen
**All vocabulary words above are found in the 7 page packet, that
starts with “The Pulmonary & Systemic Circuit”
The Pulmonary
and Systemic Circuit
The pulmonary circuit –
HEART TO LUNGS AND BACK
The systemic circuit – HEART
AND BODY AND BACK
Electrical Conduction System of the Heart
Be able to:
1. Label all electrical conducting
structures: SA Node (pacemaker), AV
Node, Bundle of His, Bundle Branches,
Purkinje fibers
2. Show the path or identify the path of
impulse conduction
3. Correlate what is occurring in these
structures to an ECG.
ECG- Electrocardiogram
What happens at the P wave?
What happens at the QRS
complex?
What occurs just after the R
wave?
What occurs at the T Wave?
Heart Sounds
• Lupp Dupp
• First heart sound (shorter)– AV valves close, semilunar valves open
• Second heart sound – Semilunar valves close
• Know all the names of the AV valves –
Left AV valve= Mitral valve, Bicuspid
Right AV valve = Tricuspid valve
The test…
• 50 + questions, 28-30 multiple choice and the rest matching and labeling
• Be able to answer questions at a higher level of thinking –
Example: (this question is NOT on the test)
The function of the chordae tendineae is to
a. anchor the semilunar valve flaps & prevent backward flow of
blood
b. anchor the AV valve flaps and prevent the backflow of blood
into the atria
c. anchor the bicuspid valve flaps and prevent backflow of blood into
ventricles
d. anchor the aortic valve flaps and prevent backflow into the
ventricles
Types of questions…
What occurs during ventricular systole?
What occurs during atrial systole?
**Notice I am not asking you to simply IDENTIFY something but you
have to know a little bit of vocabulary and APPLY what you know to
THINK THROUGH your question. Some questions may involve
sequences, some may simply be identification but BE PREPARED to
answer questions above the simple level of identification only.
Resources:
• Your Journal, E-Text, any worksheets done in class
• Youtube – Khan academy has great videos on Cardiac Cycle, heart
sounds, Heart Anatomy etc…
• Check my site for the links to the McGraw hill Animations
• THINGS TO DO:
• Quiz each other with a blank heart diagram – identify structures and path of
blood
• Quiz each other with ECG diagram, electrical conducting structures of the
heart
• Quiz each other on vocabulary
