A capillary (/ˈkæpɪlɛriz/ in US; /kəˈpɪləriz/ in UK) is a hollow tube 5 to 10 micrometres (µm) in diameter and having a wall one (endothelial) cell thick. They are the smallest blood vessels in the body: they convey blood between the arterioles and venules. These microvessels are the site of exchange of many substances with the interstitial fluid surrounding them. Substances which exit include water (proximal portion), oxygen, and glucose; substances which enter include water (distal portion), carbon dioxide, uric acid, lactic acid, urea and creatinine.[3] Lymph capillaries connect with larger lymph vessels to drain lymphatic fliud collected in the microcirculation. | A capillary (/ˈkæpɪlɛriz/ in US; /kəˈpɪləriz/ in UK) is a hollow tube 5 to 10 micrometres (µm) in diameter and having a wall one (endothelial) cell thick.
