  • 2. 

    Coronary arteries supply heart muscle with oxygen and nutrients.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because coronary arteries are responsible for supplying the heart muscle with oxygen and nutrients. These arteries branch off from the aorta and wrap around the heart, ensuring that the heart receives the necessary blood flow to function properly. Without adequate oxygen and nutrients, the heart muscle would not be able to contract effectively, leading to various heart-related issues. Therefore, the statement is correct.

    Rate this question:

  • 3. 

    The left atrium collects blood from the ______.

    • Pulmonary Veins

    • Right Atrium

    • Left Ventricle

    • Semilunar Valves

    Correct Answer
    A. Pulmonary Veins
    Explanation
    The left atrium collects blood from the pulmonary veins. The pulmonary veins carry oxygenated blood from the lungs back to the heart. Once the blood enters the left atrium, it is then pumped into the left ventricle and eventually sent out to the rest of the body through the aorta.

  • 4. 

    The heart muscle can contract by itself, without stimulation from a nerve.  This is called ______ muscle contraction.

    Correct Answer
    myogenic
    Explanation
    Myogenic muscle contraction refers to the ability of the heart muscle to contract on its own, without the need for external nerve stimulation. The heart has its own internal pacemaker, known as the sinoatrial node, which generates electrical impulses that cause the heart to contract rhythmically. This intrinsic ability of the heart to initiate and coordinate its own contractions is essential for maintaining a steady heartbeat and ensuring proper blood circulation throughout the body.

    Rate this question:

  • 5. 

    The _____ _______ collects blood from the superior and inferior vena cava.

    • Left Atrium

    • Right Atrium

    • Pulmonary Veins

    • Left Ventricle

    Correct Answer

    Explanation
    The right atrium collects blood from the superior and inferior vena cava.
