Which is r Te ari with the smallest has a diameter of approx. 0.2 mm, and the blood will flow into a capillary which is the artery that connects Venice with nun (venule) which is to replace a smaller blood vessels as possible. The blood will flow along the small blood vessels to return to the blood vessels, including a huge.
