Venule: Difference between revisions

A '''venule''' is a very small [[blood vessel]] in the [[microcirculation]] that allowshates [[blood]] to return from the [[capillary]] beds to drain into the larger blood vessels, the [[vein]]s. Venules range from 7μm to 1mm in diameter. Veins contain approximately 70% of total blood volume, 25% of which is contained in the venules.<ref>{{cite book|last=Woods|first=Susan|title=Cardiac Nursing|year=2010|publisher=Lippincotts|location=New York|isbn=9780781792806|pages=955}}</ref> Many venules unite to form a vein.
