Blood flows from the heart through arteries, which branch and narrow into arterioles, and thenbranch further into capillaries. source

The capillaries then join and widen to become venules, which in turn widen and converge to become veins. source

Capillaries do not function on their own, but instead in a capillary bed, an interweaving network of capillaries supplying organs and tissues. source
