  • 2. 
    What is #3? - ProProfs

    What is #3?

    Explanation
    The correct answer for the question "What is #3?" is the right ventricle. The chambers of the heart that are situated in the lower half of the heart are called the ventricles. This specific chamber is recognized as the right ventricle due to its placement on the patient's right-hand side.

    Rate this question:

  • 3. 
    What is #8? - ProProfs

    What is #8?

    Explanation
    The correct answer is left atrium. The chambers on the top half of the heart are called atrium, and in this context, it's identified as the left atrium due to its location on the patient's left-hand side.

    Rate this question:

  • 4. 
    What is #9? - ProProfs

    What is #9?

    Explanation
    The correct answer is the left ventricle. The heart's lower chambers are termed ventricles, and here, it's recognized as the left ventricle due to its position on the patient's left-hand side. This heart chamber pumps oxygenated blood throughout the body upon contraction.

    Rate this question:

  • 5. 
    What is #2? - ProProfs

    What is #2?

    Explanation
    The correct answer for the question "What is #2?" is the right atrium. The right atrium is positioned above the right ventricle. The upper chambers of the heart are referred to as atria, and in this context, it's identified as the right atrium due to its location on the patient's right-hand side.

    Rate this question:

  • 6. 
    What is #11? - ProProfs

    What is #11?

    Explanation
    The correct answer to this question is "vena cava inferior, IVC, or inferior vena cava." The inferior vena cava is a large vein that carries deoxygenated blood from the lower body back to the heart. It is an important component of the circulatory system and plays a crucial role in maintaining proper blood flow.

    Rate this question:

  • 7. 
    What is #4? - ProProfs

    What is #4?

    Explanation
    The tricuspid valve is the correct answer because it is one of the four valves. The heart has four valves, including the tricuspid valve, which is located between the right atrium and the right ventricle. It has three leaflets or cusps, which open and close to regulate blood flow between these two chambers. The tricuspid valve prevents the backflow of blood from the right ventricle to the right atrium during the heart's contraction, ensuring that blood flows in the correct direction.

    Rate this question:

  • 8. 
    What is #7? (Plural) - ProProfs

    What is #7? (Plural)

    Explanation
    The accurate designation for label #7 is the pulmonary veins. These vessels play a crucial role by transporting oxygenated blood back to the left atrium after it has been oxygenated in the lungs. Recognizing the function of the pulmonary veins underscores their importance in completing the oxygenation cycle within the circulatory system.

    Rate this question:

  • 9. 
    What is #6? - ProProfs

    What is #6?

    Explanation
    The correct identification for label #6 is the pulmonary artery. Functionally, it carries deoxygenated blood from the right ventricle to the lungs, where oxygenation occurs. This oxygenated blood then returns to the left side of the heart. Understanding the pulmonary artery's role in the circulatory system highlights its critical function in facilitating the oxygenation process within the body.

    Rate this question:

  • 10. 
    What is #10? - ProProfs

    What is #10?

    Explanation
    The correct answer is vena cava superior, superior vena cava. The vena cava superior, also known as the superior vena cava, is a large vein that carries deoxygenated blood from the upper body back to the heart. It is located above the right atrium and is responsible for returning blood from the head, neck, arms, and upper chest to the right atrium of the heart.

    Rate this question:

  • 11. 
    What is #5? (HINT: it's a valve) - ProProfs

    What is #5? (HINT: it's a valve)

    Explanation
    The correct answer is pulmonary valve, semilunar valve. The question asks for the identification of #5, which is a valve. The pulmonary valve is situated between the pulmonary artery and the right ventricle. This valve directs the path through which blood travels to be oxygenated by the lungs

    Rate this question:

  • 12. 
    What is #12? - ProProfs

    What is #12?

    Explanation
    The mitral valve is also known as the bicuspid valve or left atrioventricular valve. It is one of the four heart valves and lies between the left atrium and the left ventricle of the heart.
