Do You Know About The Anatomy Of The Human Heart? - Quiz

Welcome to this short assessment test of human heart anatomy. This quiz is quick in length but enough to test how much you have studied in your classes. Here are eight questions for which you have to select the correct answer, and your scores will be displayed at the end. There is no time boundary, so, take your time and answer each question!


Questions and Answers
  • 1. 

    Name the artery that carries blood from the left ventricle to the body:

    • A.

      Atria

    • B.

      Pulmonary vein

    • C.

      Semilunar valve

    • D.

      Aorta

    • E.

      None of the above

    Correct Answer
    D. Aorta
    Explanation
    The aorta is the largest artery in the body and carries oxygenated blood from the left ventricle of the heart to the rest of the body. It is responsible for delivering oxygen and nutrients to all the organs and tissues. The other options listed do not carry blood from the left ventricle to the body. The atria are the upper chambers of the heart, the pulmonary vein carries oxygenated blood from the lungs to the heart, and the semilunar valve is a valve that prevents blood from flowing back into the heart.

    What carries the oxygenated blood from the lungs to the left atrium of the heart?

    • A.

      Atria

    • B.

      Semilunar

    • C.

      Aorta

    • D.

      Pulmonary veins

    • E.

      None of the above

    Correct Answer
    D. Pulmonary veins
    Explanation
    The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.

    What acts as a "check" valve to prevent blood from flowing back into the ventricle:

    • A.

      Atria

    • B.

      Pulmonary veins

    • C.

      Atrioventricular

    • D.

      All of the above

    • E.

      None of the above

    Correct Answer
    E. None of the above
    Explanation
    The correct answer is "none of the above" because the question is asking about a structure that acts as a "check" valve to prevent blood from flowing back into the ventricle. The atria, pulmonary veins, and atrioventricular are not check valves. The correct answer would be the semilunar valves, specifically the aortic valve and the pulmonary valve, which are located between the ventricles and their respective arteries. These valves open when the ventricles contract, allowing blood to be pumped out, and close to prevent backflow when the ventricles relax.

    Two large veins that drain blood from the upper body and the lower body and empty it into the right atrium of the heart are known as the:

    Correct Answer
    posterior vena cava
    Explanation
    The two large veins that drain blood from the upper body and the lower body and empty it into the right atrium of the heart are known as the posterior vena cava. The posterior vena cava is responsible for returning deoxygenated blood from the lower body and organs, such as the legs and abdomen, back to the heart. It is one of the major veins in the body and plays a crucial role in the circulation of blood.

    Two of the four chambers with powerful muscular contractions that force blood to flow through arteries to all parts of the body:

    Correct Answer
    Ventricles
    Explanation
    The ventricles are two of the four chambers in the heart that have powerful muscular contractions. These contractions help to force blood to flow through arteries and distribute it to all parts of the body. The ventricles are responsible for pumping oxygenated blood to the body's tissues and organs, ensuring that they receive the necessary nutrients and oxygen for proper functioning.

  • 6. 

    One way valves that prevent blood flow in opposite directions (blood should flow from atria to ventricles):

    Correct Answer
    Atrioventricular Valve
    Explanation
    Atrioventricular valves are located between the atria and ventricles of the heart. These valves, including the tricuspid valve on the right side and the mitral valve on the left side, prevent the backflow of blood from the ventricles to the atria during ventricular contraction. They ensure that blood flows in a unidirectional manner, from the atria to the ventricles, allowing for efficient pumping of blood throughout the body.

      Two of four chambers (left and right). Thin-walled structures that collect blood from the major veins and empty it into the larger, more muscular ventricles:

    Correct Answer
    Atriums
    Explanation
    The correct answer is atriums. Atriums are thin-walled structures that collect blood from the major veins and empty it into the larger, more muscular ventricles. In the human heart, there are two atriums, the left atrium and the right atrium. The atriums receive oxygenated blood from the lungs (left atrium) and deoxygenated blood from the body (right atrium) and then contract to pump the blood into the ventricles. This allows for efficient blood flow throughout the body.

    Blood changes its color from blue to red in what structure?

    • A.

      Pulmonary capillary

    • B.

      Pulmonary artery

    • C.

      Aorta

    • D.

      None of above

    Correct Answer
    A. Pulmonary capillary
    Explanation
    Blood changes its color from blue to red in the pulmonary capillary.
