Concept 1: Blood Vessel Structure and Function
Blood vessels form a tubular network throughout the body that allows blood to flow from the heart to every body cell and then back to the heart.
• The three types of blood vessels are arteries, capillaries, and veins.

• Each blood vessel consists of a layered wall surrounding a central blood-containing space, or lumen.
