  • 2. 

    The heart has 3 layers of tissue:1) Epicardium: outer surface2) Myocardium: middle muscular layer &3)?

    Explanation
    The correct answer is "Endocardium." The endocardium is the innermost layer of tissue in the heart. It lines the chambers of the heart and covers the heart valves. This layer is made up of a thin layer of endothelial cells and connective tissue. The endocardium helps to prevent blood clots and provides a smooth surface for blood flow within the heart.

    Which is NOT a function of the cardiovascular system (CVS)?

    • Generating blood pressure

    • Separating pulmonary & systemic circulation

    • Regulating blood plasma volume

    • Provides nutrients to the body in the form of O2

    Correct Answer
    A. Regulating blood plasma volume
    Explanation
    The volume of blood plasma is controlled by the renal system

    What is fibrous pericardium?

    • A thin layer surrounding the heart

    • A thick inner layer of membrane protecting the heart

    • A thick outer layer of membrane surrounding the heart

    • A continuous membrane covering the heart and stops expansion

    Correct Answer
    A. A thick outer layer of membrane surrounding the heart
    Explanation
    The fibrous pericardium refers to the thick outer layer of membrane that surrounds the heart. This layer provides protection and support to the heart, helping to maintain its shape and integrity. It is composed of tough, fibrous connective tissue that helps to prevent overstretching of the heart during contractions and movements.

    Capillaries transport substances to and from cells. Select the substances below which are transferred in capillary exchange:

    • O2

    • Hormones

    • Nutrients

    • Wastes

    Correct Answer(s)
    A. O2
    A. Hormones
    A. Nutrients
    A. Wastes
    Explanation
    Capillaries are tiny blood vessels that connect arteries and veins. They play a crucial role in the exchange of substances between the blood and the surrounding cells. Oxygen (O2) is transported from the lungs to the cells through capillaries, while waste products are carried away from the cells to be eliminated. Additionally, capillaries also transport hormones, which are chemical messengers that regulate various bodily functions. Lastly, nutrients, such as glucose and amino acids, are delivered to the cells through capillaries to provide energy and support cellular processes.
