Cardiovascular System Quiz — Anatomy &
Physiology — Exam-Style Questions and
Answers for Cardiovascular System
What is the pericardium? - Correct answer- Fibrous CT covering
that encases the heart and bases of great vessels
What are the 3 cardiac layers? - Correct answer- 1- Epicardium
(visceral pericardium) Outer CT layer and mesothelium
Myocardium :
Middle cardiac muscle mass
Endocardium:
Lined with endothelium
Receives O₂ directly from blood circulating within chambers
What are non chambers structures of the heart? (1) - Correct
answer- Annulus fibrosus: CT ring (including valves) that
separates atria from ventricles
Name the different chamber structures of the heart. - Correct
answer- 1- Atria 2- Ventricles
Name the components of the atria (2) - Correct answer- 1- Atria
2 upper chambers of the heart
1|Page
,Function as low blood pressure reservoirs
2- Fossa ovalis (used in embryo)
- Located on interatrial septum
Name the components of the ventricles? (2)
***Which ventricle is a high pressure system? - Correct answer-
Components (2 lower chambers of the heart)
1) Left ventricle*** HIGH PRESSURE SYSTEM
- Circular shape with a large myocardial mass - Works much
harder than the right ventricle and more prone to disease
processes
2) Right ventricle
generates a low pressure
Pumps the same volume of blood as the left ventricle!
Interventricular septum separates the right and left ventricles
Name the heart chamber structures (2) - Correct answer- 1-
Papillary muscles: 3 on the right and 2 on the left
2- Chordae tendineae: Attaches the papillary muscles to
respective atrioventricular (AV) valve leaflets
Name the 2 chamber valves - Correct answer- 1- Atrioventricular
valves
Tricuspid
,Mitral valve
2- Semilunar values: Aortic and pulmonary valve
Name the atrioventricular valves? (2) - Correct answer- 1-
Tricuspid valve: separates the right atrium from the right
ventricle
2- Mitral valve: Separates the left ventricle from the left ventricle
What is the function of the atrioventricular values? (3) - Correct
answer- 1- Open during diastole (ventricular relaxation)
Close during systole (ventricular contraction)
Prevents backward flow (regurgitation) of blood from the
ventricles to the atria
Name the semilunar valves (2) - Correct answer- 1- Aortic valves:
allows blood flow from the left ventricle into the systemic circuit
2- Pulmonic valve: Allows blood to flow from the right ventricle
into the pulmonary circuit.
What is the function of the semilunar valves? (3) - Correct answer-
1- Open during systole
Closed during diastole
, Prevents regurgitation of blood into the ventricles
Name the components responsible for pulmonary and systemic
circulation (2)
True or false
Cardiac output of the right heart = cardiac output of the left heart
- Correct answer- Pulmonary circulation: the right atrium and
right ventricle
Systemic circulation: left atrium and left ventricle
2- TRUE!
Cardiac output of the right heart= cardiac output of the left heart
Describe the path of blood flow in the heart
Name the three branches on top of the aorta (from left to right) -
Correct answer- Branches on top of the aorta (left to right)
Brachiocephalic → common cartoid → subclavian
****TEST QUESTION****
The heart receives its own blood supply during ___________.
O₂ extraction from coronary arteries is _______.
