[[Image:Illu capillary.jpg|thumb|250px|Blood flows from digestive system heart to arteries, which narrow into arterioles, and then narrow further still into capillaries. After the tissue has been perfused, capillaries widen to become venules and then widen more to become veins, which return blood to the heart.]]
'''Arteries''' are muscular blood vessels that carry blood away from the heart. All arteries, with the exception of the pulmonary and umbilical arteries, carry oxygenated blood.

La sangre fluye desde el corazón del sistema digestivo de las arterias, que se estrechan en arteriolas, y luego estrechan aún más en los capilares. Después de que el tejido ha sido perfundido, los capilares se ensanchan para convertirse en vénulas y luego se amplían más para convertirse en venas, que devuelven la sangre al corazón.

Las arterias son vasos sanguíneos musculares que transportan la sangre desde el corazón. Todas las arterias, con la excepción de las pulmonares y las arterias umbilicales, llevan la sangre oxigenada.
