Get Ready For A Quick Cardiovascular System Quiz!
The cardiovascular system in our body is tasked with regulating blood flow and ensuring that every part of the body gets blood. The main components of this system are the heart, blood, and blood vessels. The quiz below is all about the system and all we learned about it. Give it a shot and see what you remember before the exam!

The muscular layer of the heart that is responsible for pumping is the:
- A.
Endocardium
- B.
Epicardium
- C.
Myocardium

This chamber of the heart is much thicker than the others because it pumps to the entire body:
- A.
Right atrium
- B.
Right ventricle
- C.
Left atrium
- D.
Left ventricle

Why is the mitral valve different from the other three valves of the heart?
- A.
It only has 1 flap
- B.
It only has 2 flaps
- C.
It only has 3 flaps
Correct Answer
B. It only has 2 flapsExplanation
The correct answer is that the mitral valve only has 2 flaps. Unlike the other three valves of the heart, which typically have three flaps, the mitral valve is unique in having only two flaps. This difference in the number of flaps contributes to the distinct structure and function of the mitral valve, allowing it to regulate the flow of blood between the left atrium and left ventricle of the heart.Rate this question:

The correct pathway that an erythrocyte would travel during systemic circulation is:
- A.
Arteriole--aorta--vein--venule--capillary
- B.
Capillary--venule--vein--artery--aorta
- C.
Aorta--arteriole--capillary--venule--vein
- D.
Venule--vein--capillary--arteriole--aorta
Correct Answer
C. Aorta--arteriole--capillary--venule--veinExplanation
aorta leaves the heart, arteries away from the heart to capillaries, venules leave the capillaries and veins to the heart.Rate this question:

The vessel layer that is fibrous and responsible for support is the:
- A.
Tunica externa
- B.
Tunica intima
- C.
Tunica media
Correct Answer
A. Tunica externaExplanation
The tunica externa is the correct answer because it is the outermost layer of blood vessels and is composed of fibrous connective tissue. This layer provides strength and support to the vessel, helping to maintain its shape and integrity. The tunica externa also contains blood vessels that supply nutrients to the vessel wall.Rate this question:

The softer "dupp" sound of the heart is from:
- A.
The closing of the atrioventricular valve
- B.
The closing of the semilunar valve
- C.
The opening of the semilunar valve
Correct Answer
B. The closing of the semilunar valveExplanation
The softer "dupp" sound of the heart is produced by the closing of the semilunar valve. This valve is located between the ventricles and the major arteries leaving the heart. When the ventricles relax and blood starts to flow back towards the heart, the semilunar valve closes to prevent the backflow of blood. This closure creates the softer sound known as the second heart sound or "dupp". The closing of the atrioventricular valve, on the other hand, produces the first heart sound or "lubb".Rate this question:

The umbilical cord has a vein that carries:
- A.
Nutrients and oxygen rich blood to the baby
- B.
Wastes from the mom
- C.
Carbon dioxide and metabolic materials to the baby
Correct Answer
A. Nutrients and oxygen rich blood to the babyExplanation
The umbilical cord carries nutrients and oxygen-rich blood to the baby. This is essential for the baby's growth and development as it provides the necessary nourishment and oxygen for the baby's cells and organs to function properly. The umbilical cord acts as a lifeline between the mother and the baby, allowing the transfer of these vital substances from the mother's bloodstream to the baby's bloodstream.Rate this question:
