    Chapter Learning Objectives

    imageBy the end of this chapter, you should be able to do the following:

    • Describe the different components of the circulatory system.
    • Identify the tunica intima, tunica media, and tunica adventitia, naming the major components of each.
    • Describe how the vascular tunics differ at different levels of the vasculature (ie. artery vs. vein)
    • Explain the structure and function of endothelial cells.
    • Describe the differences in structure between arteries, arterioles, metarterioles, capillaries, venules, veins and lymphatics.
    • Explain the differences between continuous, fenestrated and sinusoidal capillaries.
    • Describe the structures that comprise the heart.
    • List the microscopic differences between skeletal and cardiac muscle
