    About the Lecture

    The lecture Cardiovascular System: Vessels by Geoffrey Meyer, PhD is from the course Cardiovascular Histology. It contains the following chapters:

    • Cardiovascular System: Vessels
    • The wall of an artery and vein
    • Small and large arteries
    • The pericyte
    • Differences between small artery and small venule
    • The aorte
    • The vena cava
    • Capillary
    • Three types of capillaries
    • Lymphatic vessels
    • Summary - Arteries, veins, capillaries and lymph vessels

    Included Quiz Questions

    1. called the systolic pressure and is about 120 mmHg
    2. called the diastolic pressure and is about 80 mmHg
    3. called the systolic pressure and is about 80 mmHg
    4. called the diastolic pressure and is about 120 mmHg
    5. the same as the pressure inside the superior and inferior vena cava
    1. the layer of tissue immediately adjacent to the luminal aspect (near the blood) of the tunica media is the internal elastic lamina
    2. it is easy to differentiate the tunica adventitia from the tunica media and also surrounding connective tissue that binds the artery to adjacent structures
    3. the tunica intima is usually as thick as the tunica media
    4. the external elastic lamina separates the tunica adventitia from surrounding connective tissue that binds the artery to adjacent structures
    5. the thinnest layer is the tunica media
    1. Smooth muscle fibres in the tunica adventitia of the inferior vena cava are arranged longitudinal to the length of the vessel
    2. Smooth muscle fibres in the tunica media of the inferior vena cava are arranged longitudinal to the length of the vessel
    3. Like all veins, there are no smooth muscle fibres in the tunica adventitia of the vena cava
    4. Elastic fibres in the tunica intima of the aorta aid in the recoil action of the artery's wall to maintain pressure and therefore flow along this vessel
    5. Elastic fibres in the tunica adventitia of the aorta aid in the recoil action of the artery's wall to maintain pressure and therefore flow along this vessel
    1. kidney
    2. skin
    3. spleen
    4. endocrine organ
    5. brain
