Capillaries (blood)

Definition (http://en.wikipedia.org/wiki/Capillaries)

Capillaries are the smallest of a body's blood vessels and are parts of the microcirculation. Their endothelial linings are only one cell layer thick. These microvessels, measuring 5-10 µm in diameter, connect arterioles and venules, and enable the exchange of water, oxygen, carbon dioxide, and many other nutrients and waste chemical substances between blood and surrounding tissues.
