General Components Of The Vascular Network

Following what we see in Figure 11.1, the vascular network includes the arteries, arterioles (ar-TEER-ee-ohls), capillary (CAP-ih-lair-ee) network, venules (VEN-yools), and finally, the veins.

Summarizing these components, we obtain:

THE VASCULAR - ARTERIES + ARTERIOLES + CAPILLARY (BLOOD VESSEL) NETWORK + VENULES + VEINS NETWORK

Finally, blood connective tissue is the material which is pumped in a ''little circle'' through the vascular network. As the blood circulates, it provides nutrients to the cells of most body tissues, and then picks up metabolic waste products from them. The force for pumping the blood comes, of course, from the contracting muscle tissue within the walls of the heart.
