Microvasculature

Extracted from the Wikipedia article Microcirculation.
The microcirculation is the circulation of the blood in the smallest blood vessels, the microvessels of the microvasculature present within organtissues. The microvessels include terminal arterioles, metarterioles, capillaries, and venules. Arterioles carry oxygenated blood to the capillaries, and blood flows out of the capillaries through venules into veins.
