Question 5.
What are the three layers of the heart?
ANSWER
1. Endocardium
2. Myocardium
3. Epicardium (Pericardium)
Question 6.
What is the Endocardium layer of the heart?
ANSWER
It the inner layer if the heart wall.
, Question 7.
What is the function of the Endometrium?
ANSWER
1. It forms the inner lining of the heart wall --> Promoting Laminar Blood flow though the heart.
2. It also forms the heart Valves.
Question 8.
What is the Myocardium layer of the heart?
ANSWER
The middle layer of the heart: Is the Muscle that pumps the blood forward
Question 9.
What is the Epicardium layer of the heart?
ANSWER
It is the outer layer of the heart wall that consist of connective tissue this forms the pericardial sac.
Question 10.
What is the pericardial sac of the heart?
ANSWER
It is a protective layer containing fluid allowing the heart to function without friction.
Question 11.
What are the structures that forms the heart valves?
ANSWER
1. Leaflet (flaps)
2. Chordae Tendineae
3. Papillary Muscles
Question 12.
What is the function of the heart?
ANSWER
Controls the direction of the blood flow though the heart, thus preventing flowing backwards (regurgitation) of blood.
Question 13.
What are the names of the four valves of the heart?
ANSWER
1. Tricuspid Valve
2. Pulmonary Valve
3. Mitral Valve
4. Aortic Valve Synchronized valve closure preventing blood from flowing backwards.
, Question 14.
What are the names of the Atrioventricular Valves?
ANSWER
1. Tricuspid Valves (right side)
2. Mitral Valves (left side)
Question 15.
What are the names of the semilunar Valves?
ANSWER
1. Pulmonary Valve (Right side)
2. Aortic Valve (Left side)
Question 16.
State the Right sided blood flow in order?
ANSWER
1. Superior and Inferior Vena Cava
2. Right Atrium
3. Tricuspid Valve
4. Right Ventricle
5. Pulmonary Valves
6. Pulmonary Artery
7. Lungs
Question 17.
State the Left sided blood flow in order?
ANSWER
1. Lungs
2. Right and Left Pulmonary Veins
3. Left Atrium
4. Mitral Valve
5. Left Ventricles
6. Aortic Valve
7. Aorta
Question 18.
What are the Physiological aspects of the Coronary Artery System?
ANSWER
It 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.
