Anatomy Of Heart Quiz! #2 - Quiz

Welcome to part 2 of the Anatomy of Heart Quiz! There are a lot of things that we got to understand about the heart in the previous chapter. And this includes its functions and how to identify when something is not going right with it. Do you feel like you know all there is to the chambers of the heart, their names, and how they attain their functions? Take up the quiz below and test your knowledge!


Questions and Answers
  • 1. 

    What are the four chambers of the heart?

    Explanation
    The four chambers of the heart are the right atria, left atria, right ventricle, and left ventricle. The atria are the upper chambers of the heart, responsible for receiving blood from the veins. The right atria receives deoxygenated blood from the body, while the left atria receives oxygenated blood from the lungs. The ventricles are the lower chambers of the heart, responsible for pumping blood out of the heart. The right ventricle pumps deoxygenated blood to the lungs, while the left ventricle pumps oxygenated blood to the rest of the body.

    Which chamber of the heart recieves blood from the superior and inferior venae cavae?

    • A.

      Right atria

    • B.

      Left atria

    • C.

      Right Ventricle

    • D.

      Left Ventricle

    Correct Answer
    A. Right atria
    Explanation
    The right atria is the chamber of the heart that receives blood from the superior and inferior vena cavae. The vena cavae are large veins that carry deoxygenated blood from the body back to the heart. Once the blood enters the right atria, it is then pumped into the right ventricle and eventually sent to the lungs for oxygenation. Therefore, the correct answer is right atria.

    Which chamber recieves blood from the pulmonary veins?

    • A.

      Right atria

    • B.

      Left atria

    • C.

      Right Ventricle

    • D.

      Left Ventricle

    Correct Answer
    B. Left atria
    Explanation
    The left atria receives blood from the pulmonary veins. The pulmonary veins carry oxygenated blood from the lungs back to the heart. The left atria then pumps this oxygenated blood into the left ventricle, which in turn pumps the blood out to the rest of the body.

      Right Ventricle

    • D.

      Left Ventricle

    Correct Answer
    C. Right Ventricle
    Explanation
    The right ventricle pumps blood into the pulmonary trunk. The pulmonary trunk is a large blood vessel that carries deoxygenated blood from the heart to the lungs for oxygenation. The right ventricle receives deoxygenated blood from the right atrium and contracts to push the blood into the pulmonary trunk. From there, the blood is transported to the lungs where it picks up oxygen and gets rid of carbon dioxide.

      Right atria

    • B.

      Left atria

    • C.

      Right Ventricle

    • D.

      Left Ventricle

    Correct Answer
    D. Left Ventricle
    Explanation
    The left ventricle is the chamber of the heart that pumps oxygenated blood into the aorta. It receives blood from the left atrium and contracts to push the blood out into the body's largest artery, the aorta. The aorta then distributes the oxygenated blood to the rest of the body.

    Rate this question:

  • 6. 

    Which valve is located between the right artia and the right ventricle?

    • A.

      Tricuspid

    • B.

      Bicuspid

    • C.

      Aortic

    • D.

      Pulmonary

    Correct Answer
    A. Tricuspid
    Explanation
    The tricuspid valve is located between the right atria and the right ventricle. It is called tricuspid because it consists of three flaps or cusps. This valve prevents the backflow of blood from the right ventricle to the right atria during the contraction of the heart. When the right atria contracts, the tricuspid valve opens, allowing blood to flow into the right ventricle. When the right ventricle contracts, the tricuspid valve closes, preventing blood from flowing back into the right atria.

    • C.

      Aortic

    • D.

      Pulmonary

    Correct Answer
    B. Bicuspid
    Explanation
    The bicuspid valve, also known as the mitral valve, is located between the left atria and the left ventricle. This valve allows blood to flow from the left atrium into the left ventricle, preventing any backflow of blood.

      Bicuspid

    • C.

      Aortic

    • D.

      Pulmonary

    Correct Answer
    D. Pulmonary
    Explanation
    The correct answer is pulmonary because the pulmonary valve is located between the right ventricle and the pulmonary trunk. This valve prevents the backflow of blood from the pulmonary trunk into the right ventricle, ensuring that blood flows only in one direction, from the right ventricle to the pulmonary trunk and then to the lungs for oxygenation.

    Rate this question:

  • 10. 

    What is the purpose of the valve?

    Correct Answer
    prevent back flow of blood
    Explanation
    The purpose of the valve is to prevent the backflow of blood. Valves are present in various parts of the circulatory system, such as the heart and veins, and they ensure that blood flows in one direction. In the case of preventing backflow, the valve acts as a barrier that closes when the blood tries to flow in the wrong direction, thus maintaining the proper flow of blood through the circulatory system.

  • 11. 

    What vessel takes blood from the heart to the lungs?

    • A.

      Arteries

    • B.

      Veins

    Correct Answer
    A. Arteries
    Explanation
    Arteries are the blood vessels that carry oxygenated blood away from the heart to the rest of the body. However, in the case of the question, it is incorrect to say that arteries take blood from the heart to the lungs. The correct answer should be veins, as pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the heart.

    Rate this question:

  • 12. 

    What vessel takes blood from the lungs to the heart?

    • A.

      Arteries

    • B.

      Veins

    Correct Answer
    B. Veins
    Explanation
    Veins are the blood vessels that carry blood from the lungs back to the heart. After blood has been oxygenated in the lungs, it is collected by the pulmonary veins and transported back to the heart to be pumped to the rest of the body. Arteries, on the other hand, carry oxygenated blood away from the heart to the rest of the body. Therefore, the correct answer is veins.

    Rate this question:

  • 13. 

    Where are veins oxygenated?

    Correct Answer
    capillary beds of lungs
    Explanation
    Veins are blood vessels that carry deoxygenated blood back to the heart. Oxygenation of blood occurs in the capillary beds of the lungs. In the lungs, deoxygenated blood from the veins is exposed to oxygen in the air sacs called alveoli. Oxygen diffuses across the thin walls of the capillaries and binds to red blood cells, while carbon dioxide, a waste product, is released from the blood into the alveoli to be exhaled. Therefore, the capillary beds of the lungs are where veins become oxygenated.

    F. Carry blood way from heart
    G. Tunics
    Explanation
    Arteries are blood vessels that carry oxygenated blood away from the heart to various parts of the body. They do not have valves, unlike veins which have valves to prevent backflow of blood. The smallest branches of arteries are called arterioles, which further divide into capillaries. Arteries carry blood away from the heart, while veins carry blood towards the heart. Arteries are composed of three layers called tunics, which are the tunica intima, tunica media, and tunica externa.

      Tunics

    Correct Answer(s)
    B. Valves
    D. Smallest branch are venues
    E. Carry blood toward heart
    G. Tunics
    Explanation
    Veins have valves, which help to prevent the backflow of blood and ensure that it flows in one direction towards the heart. The smallest branches of veins are called venules, not arterioles. Veins carry blood towards the heart, while arteries carry blood away from the heart. Veins also have tunics, which are layers of tissue that make up their walls.

    What is the smallest vessel?

    • A.

      Capillaries

    • B.

      Veins

    • C.

      Arteries

    Correct Answer
    A. Capillaries
    Explanation
    Capillaries are the smallest vessels in the body. They are tiny, thin-walled blood vessels that connect arteries and veins. Capillaries play a crucial role in the exchange of oxygen, nutrients, and waste products between the blood and the surrounding tissues. Due to their small size, capillaries have a large surface area, allowing for efficient exchange of substances. Veins and arteries are larger vessels that carry blood to and from capillaries, but they are not the smallest vessels in the body.

    What is opposition of flow reffered to as?

    • A.

      Peripheral resistance

    • B.

      Cardiac output

    • C.

      Blood valve

    Correct Answer
    A. Peripheral resistance
    Explanation
    Peripheral resistance refers to the opposition of flow in the blood vessels, which is the correct answer in this case. It represents the resistance that the blood encounters as it flows through the arteries, arterioles, capillaries, venules, and veins. This resistance is primarily determined by the diameter of the blood vessels, the viscosity of the blood, and the length of the vessels. When peripheral resistance is high, it can lead to increased blood pressure and strain on the heart. Therefore, peripheral resistance plays a crucial role in regulating blood flow and maintaining cardiovascular health.

    What prevents backflow into the left artrium

    • A.

      Mitral Valve

    • B.

      Tricuspid Valve

    • C.

      Aortic Valve

    • D.

      Pulmonary Valve

    Correct Answer
    A. Mitral Valve
    Explanation
    The mitral valve prevents backflow into the left atrium. It is located between the left atrium and the left ventricle of the heart. When the left ventricle contracts, the mitral valve closes to prevent blood from flowing back into the left atrium. This ensures that blood flows in one direction, from the left atrium to the left ventricle, and then out to the rest of the body.

    A blood hemorrhage would result in a

    • A.

      Lower BP

    • B.

      Higher BP

    • C.

      No change

    Correct Answer
    A. Lower BP
    Explanation
    A blood hemorrhage would result in a lower blood pressure because the loss of blood volume leads to a decrease in the overall pressure within the circulatory system. When blood is lost, there is less fluid available to fill the blood vessels, causing a drop in blood pressure. This can lead to symptoms such as dizziness, weakness, and fainting.

    Rate this question:

  • 23. 

    The mitral valve has chordae tendonae but the tricupsid does not

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement is false because both the mitral valve and the tricuspid valve have chordae tendineae. Chordae tendineae are fibrous cords that connect the valve leaflets to the papillary muscles in the heart. They help to prevent the valve leaflets from prolapsing or inverting into the atria during ventricular contraction. Therefore, both the mitral valve and the tricuspid valve rely on chordae tendineae for proper functioning.

    Cardiac output is _____ to heart rate.

    • A.

      Directly related, as one increases so does the other

    • B.

      Indirectly related, as one increases one decreases

    Correct Answer
    A. Directly related, as one increases so does the other
    Explanation
    Cardiac output is directly related to heart rate, meaning that as heart rate increases, so does cardiac output. This is because cardiac output is the amount of blood pumped by the heart per minute, and heart rate is the number of times the heart beats per minute. Therefore, when heart rate increases, the heart pumps more blood per minute, resulting in an increase in cardiac output.

    Rate this question:

  • 25.

    • A.

      Artioles

    • B.

      Capillaries

    • C.

      Large Veins

    • D.

      Large Arteries

    Correct Answer
    C. Large Veins
    Explanation
    Large veins have the greatest blood volume because they receive blood from capillaries and smaller veins and transport it back to the heart. The walls of large veins are thin and elastic, allowing them to accommodate a large volume of blood. In contrast, arteries carry blood away from the heart, and while they may have a high blood pressure, their volume is lower than that of large veins. Capillaries, on the other hand, are the smallest blood vessels and have a small volume compared to large veins. Therefore, large veins have the greatest blood volume.

    Rate this question:

  • 26. 

    What is not one of the main factors affecting blood pressure?

    • A.

      Cardiac output

    • B.

      Peripheral resistance

    • C.

      Emotional state

    • D.

      Blood Volume

    Correct Answer
    C. Emotional state
    Explanation
    Emotional state is not one of the main factors affecting blood pressure. Blood pressure is primarily influenced by factors such as cardiac output, peripheral resistance, and blood volume. Cardiac output refers to the amount of blood pumped by the heart per minute, while peripheral resistance refers to the resistance encountered by blood flow in the blood vessels. Blood volume refers to the total amount of blood in the body. Although emotional state can temporarily affect blood pressure, it is not considered one of the main factors.
