cappillaries

==============

The smallest veins in the body are the venules. Capillaries join venules and arterioles (the smallest arteries) together. Arteries carry the blood from the heart around the whole body; while veins carry the blood back to the heart. They are joined by the capillaries, where the most important actions happen.
