CORRECT!!
What are the four chambers of the heart? - ANSWER1. Right Atrium
2. Right Ventricle
3. Left Atrium
4. Left Ventricle
What is the Endocardium layer of the heart? - ANSWERIt the inner layer if the heart
wall.
What is the function of the Endometrium? - ANSWER1. It forms the inner lining of
the heart wall --> Promoting Laminar Blood flow though the heart.
2. It also forms the heart Valves.
What is the Myocardium layer of the heart? - ANSWERThe middle layer of the heart:
Is the Muscle that pumps the blood forward
What is the Epicardium layer of the heart? - ANSWERIt is the outer layer of the heart
wall that consist of connective tissue this forms the pericardial sac.
What is the name of the Structure dividing the Heart Chambers into the right and left
Heart? - ANSWERSeptum
What is the function of the Right side of the heart? - ANSWERPumps blood to the
Lungs
What is the function of the Left side of the heart? - ANSWERPumps blood to the
body
What are the three layers of the heart? - ANSWER1. Endocardium
2. Myocardium
3. Epicardium (Pericardium)
What is the pericardial sac of the heart? - ANSWERIt is a protective layer containing
fluid allowing the heart to function without friction.
What are the structures that forms the heart valves? - ANSWER1. Leaflet (flaps)
2. Chordae Tendineae
3. Papillary Muscles
What is the function of the heart? - ANSWERControls the direction of the blood flow
though the heart, thus preventing flowing backwards (regurgitation) of blood.
, What are the names of the four valves of the heart? - ANSWER1. Tricuspid Valve
2. Pulmonary Valve
3. Mitral Valve
4. Aortic Valve
Synchronized valve closure preventing blood from flowing backwards.
What are the names of the Atrioventricular Valves? - ANSWER1. Tricuspid Valves
(right side)
2. Mitral Valves (left side)
What are the names of the semilunar Valves? - ANSWER1. Pulmonary Valve (Right
side)
2. Aortic Valve (Left side)
State the Right sided blood flow in order? - ANSWER1. Superior and Inferior Vena
Cava
2. Right Atrium
3. Tricuspid Valve
4. Right Ventricle
5. Pulmonary Valves
6. Pulmonary Artery
7. Lungs
State the Left sided blood flow in order? - ANSWER1. Lungs
2. Right and Left Pulmonary Veins
3. Left Atrium
4. Mitral Valve
5. Left Ventricles
6. Aortic Valve
7. Aorta
What are the Physiological aspects of the Coronary Artery System? - ANSWERIt is a
low-pressure system, with coronary arteries arise from the root of the Aorta.
The flow of blood occurs during diastole.
During Systole:
1. Aortic Valve occlude the orifices
2. Pressure rises making the coronary vessels tortuous.
The Anatomy of the Coronary Artery System: What are the names of the arteries? -
ANSWER1. Right Coronary Artery:
a. Posterior Descending artery
b. Right Marginal Artery
2. Left Coronary Artery
a. Left Circumflex Artery
b. Left Marginal Artery
c. Left Anterior Descending artery
d. Diagonal Branch
