flows from the heart to arteries‚ which branch and narrow into arterioles‚ and then narrow further still into capillaries. After the tissue has been perfused‚ capillaries branch and widen to become venules and then widen more and connect to become veins‚ which return blood to the heart. Capillaries (pronounced /ˈkæpəˌlɛri/) are the smallest of a body ’s blood vessels and are part of the microcirculation. They are only 1 cell thick. These microvessels‚ measuring 5-10 μm in diameter‚ connect arterioles
