About This 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.

    The muscular layer of the heart that is responsible for pumping is the:

    • Endocardium

    • Epicardium

    • Myocardium

    Correct Answer
    A. Myocardium
    Explanation
    the endocardium is the internal lining; the epicardium is the external surface.

    What part of the intrinsic conduction system starts the heart beat?

    • The atrioventricular node

    • The Bundle of His

    • The Perkinje fibers

    • The sino-atrial node

    Correct Answer
    A. The sino-atrial node
    Explanation
    the correct sequence is sinoatrial node, atrioventricular node, Bundle of His,  Purkinje  fibers.

    This chamber of the heart is much thicker than the others because it pumps to the entire body:

    • Right atrium

    • Right ventricle

    • Left atrium

    • Left ventricle

    Correct Answer
    A. Left ventricle
    Explanation
    the right side of the heart pumps to the lungs; the atria receives blood

    • 120/80

    • 170/120

    • 80/65

    Correct Answer
    A. 80/65
    Explanation
    120/80 is normal.

    Why is the mitral valve different from the other three valves of the heart?

    • It only has 1 flap

    • It only has 2 flaps

    • It only has 3 flaps

    Correct Answer
    A. It only has 2 flaps
    Explanation
    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.

    You can check the pulse n your neck using the:

    • Brachial artery

    • Jugular vein

    • Carotid artery

    • Popliteal vein

    Correct Answer
    A. Carotid artery
    Explanation
    pulse is taken in an artery, brachial in the arm

    The correct pathway that an erythrocyte would travel during systemic circulation is:

    • Arteriole--aorta--vein--venule--capillary

    • Capillary--venule--vein--artery--aorta

    • Aorta--arteriole--capillary--venule--vein

    • Venule--vein--capillary--arteriole--aorta

    Correct Answer
    A. Aorta--arteriole--capillary--venule--vein
    Explanation
    aorta leaves the heart, arteries away from the heart to capillaries, venules leave the capillaries and veins to the heart.

    The softer "dupp" sound of the heart is from:

    • The closing of the atrioventricular valve

    • The closing of the semilunar valve

    • The opening of the semilunar valve

    Correct Answer
    A. The closing of the semilunar valve
    Explanation
    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".

    • Visceral pericardium

    • Parietal pericardium

    • Visceral peritoneum

    • Parietal peritoneum

    Correct Answer
    A. Parietal pericardium
    Explanation
    the peritoneum is found in the abdomen; the visceral membranes are found on the surface of structures.

    The vessel layer that is fibrous and responsible for support is the:

    • Tunica externa

    • Tunica intima

    • Tunica media

    Correct Answer
    A. Tunica externa
    Explanation
    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.
