Heart Anatomy Quiz - Are You A Heart Doctor? - Quiz

The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.

Label each part of heart based on question number; each labeled number corresponds to label on picture


Questions and Answers
  • 1. 

    Label 5. 

    Explanation
    The correct answer is Right Atrium because the question asks for the label of the structure, and "Right Atrium" is the label given for that specific structure.

    Rate this question:

  • 2. 

    Label 7 

    Explanation
    The label "Right Ventricle" is correct because it accurately identifies the chamber of the heart that is responsible for pumping oxygen-depleted blood to the lungs. The right ventricle receives blood from the right atrium and contracts to push the blood through the pulmonary artery and into the lungs for oxygenation. This label is consistent with the anatomical location and function of the right ventricle.

    Rate this question:

  • 3. 

    Label 14. 

    Explanation
    The given correct answer is "Left Ventricle." This suggests that the label 14 corresponds to the left ventricle in a diagram or image. The left ventricle is one of the four chambers of the heart and is responsible for pumping oxygenated blood to the rest of the body.

    Rate this question:

  • 4. 

    Label 11. 

    Explanation
    The correct answer is "Left Atrium." The left atrium is one of the four chambers of the heart. It receives oxygenated blood from the lungs and pumps it into the left ventricle, which then sends the blood to the rest of the body. The left atrium is responsible for receiving and storing the oxygenated blood before it is pumped out of the heart.

    Rate this question:

  • 5. 

    Label 4 + 10. 

    Explanation
    The correct answer is "Pulmonary Veins, right and left pulmonary veins". The question is asking for the label of the structure indicated by "4 + 10". The only option that matches this description is the pulmonary veins, specifically the right and left pulmonary veins.

    Rate this question:

  • 6. 

    Label 3. 

    Explanation
    The right branch of the pulmonary artery refers to one of the two main branches that arise from the pulmonary trunk. The pulmonary trunk is a large blood vessel that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. The right branch of the pulmonary artery specifically supplies blood to the right lung, while the left branch supplies blood to the left lung. These branches further divide into smaller arteries to distribute blood throughout the lung tissue.

    Rate this question:

  • 7. 

    Label 9 

    Explanation
    The left branch of the pulmonary artery refers to one of the two main branches that arise from the pulmonary trunk. The pulmonary trunk is a major blood vessel that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. The left branch of the pulmonary artery specifically carries blood to the left lung. It is important for the proper oxygenation of blood and the functioning of the respiratory system.

    Rate this question:

  • 8. 

    F the aortic arch and pulmonaryarteries were connected, what would it be called? 

    Explanation
    If the aortic arch and pulmonary arteries were connected, it would be called ductus arteriosus. Ductus arteriosus is a blood vessel that connects the pulmonary artery to the descending aorta in fetal circulation. It allows blood to bypass the lungs since the fetus receives oxygen from the mother's placenta. After birth, the ductus arteriosus normally closes, redirecting blood flow to the lungs for oxygenation. However, in some cases, the ductus arteriosus remains open, causing a condition called patent ductus arteriosus (PDA).

    Rate this question:

  • 9. 

    Label 1. 

    Explanation
    The correct answer is Aortic arch. The aortic arch is a curved blood vessel that extends from the heart and gives rise to several major arteries that supply blood to the head, neck, and upper limbs. It is an important structure in the circulatory system, allowing blood to be distributed to these areas efficiently.

    Rate this question:

  • 10. 

    Label the first artery on the arotic arch. 

    Explanation
    The correct answer is "Brachiocephalic trunk." The brachiocephalic trunk is the first artery that branches off from the aortic arch. It is responsible for supplying blood to the right subclavian artery and the right common carotid artery.

    Rate this question:

  • 11. 

    Label the last artery on the arotic arch. 

    Explanation
    The left subclavian artery is labeled as the last artery on the aortic arch. The aortic arch is a curved part of the aorta that gives rise to several major arteries, including the brachiocephalic trunk, left common carotid artery, and left subclavian artery. The left subclavian artery is the final branch of the aortic arch and supplies blood to the left arm and parts of the brain. Therefore, it is correctly identified as the last artery on the aortic arch.

    Rate this question:

  • 12. 

    Label 2. 

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

    Rate this question:

  • 13. 

    Where does 9. go?. 

    Explanation
    The correct answer is the left bronchus. The question is asking about the location of something, specifically "9.". Since the left bronchus is mentioned in the question, it can be inferred that "9." refers to the left bronchus. Therefore, the correct answer is the left bronchus.

    Rate this question:

  • 14. 

    Where does 3 go to?. 

    Explanation
    The question is asking about the destination of "3". Although the question is incomplete and lacks context, it can be inferred that "3" refers to something that is being moved or directed. Since the answer provided is "right bronchus", it suggests that "3" is being directed towards or going to the right bronchus.

    Rate this question:

  • 15. 

    Label 6. 

    Explanation
    The correct answer is tricuspid valve. The tricuspid valve is a valve located between the right atrium and the right ventricle of the heart. It consists of three cusps or flaps that open and close to regulate blood flow. When the right atrium contracts, the tricuspid valve opens, allowing blood to flow into the right ventricle. When the right ventricle contracts, the tricuspid valve closes to prevent blood from flowing back into the atrium. This valve plays a crucial role in ensuring proper blood circulation within the heart.

    Rate this question:

  • 16. 

    Label the structure connecting the right venticle and the pulmonary artery. 

    Explanation
    The structure connecting the right ventricle and the pulmonary artery is called the pulmonary valve. This valve is responsible for allowing blood to flow from the right ventricle into the pulmonary artery, which carries oxygen-depleted blood to the lungs for oxygenation. The pulmonary valve prevents the backflow of blood into the right ventricle when the heart contracts, ensuring that blood flows in the correct direction.
