Module 4: Cadiovascular II Blood Vessels

Figure 4.1 Blood Vessels.  While most blood vessels are located deep from the surface and are not visible, the superficial veins of the upper limb provide an indication of the extent, prominence, and importance of these structures to the body. (credit: Colin Davis)

Module Overview

The cardiovascular system's blood vessels are essential delivery systems. They form an intricate tubule network that transports blood throughout your body, delivering oxygen and nutrients while removing waste.  Blood vessels are essential for keeping every organ and tissue alive and functioning.  There are three main types of blood vessels, each with a distinct role.  Arteries carry oxygen-rich blood away from the heart to the body.  Veins return oxygen-poor blood back to the heart after systemic circulation.  Capillaries are tiny vessels that connect arteries and veins, allowing the exchange of gases, nutrients, and waste between blood and tissues.
