Guest guest Posted May 11, 2012 Report Share Posted May 11, 2012 see microcirculation, wiki The blood flows from venules into the veins. In addition to these blood vessels, the microcirculation also includes lymphatic capillaries and collecting ducts. The main functions of the microcirculation include the regulation of 1. blood flow and tissue perfusion 2. blood pressure, 3. tissue fluid (swelling or edema), 4. delivery of oxygen and other nutrients and removal of CO2 and other metabolic waste products, and 5. body temperature. The microcirculation also has an important role in inflammation. Most vessels of the microcirculation are lined by flattened cells, the endothelium and many are surrounded by contractile cells the smooth muscle or pericytes. The endothelium provides a smooth surface for the flow of blood and regulates the movement of water and dissolved materials in the plasma between the blood and the tissues. The endothelium also produce molecules that discourage the blood from clotting unless there is a leak. The smooth muscle cells can contract and decrease the size of the arterioles and thereby regulate blood flow and blood pressure. I " M CURIOUS ABOUT THE LAST 2 LINES ABOVE " unless there is a leak " what is leaking, and do we wiht cfs have a leak? do we have problems wiht the smooth muscle cells they list microcirculation journal at this wiki page also Sadly, the below researcher of microcirculation died in surgery http://www.independent.com/news/2012/may/10/westmont-mourns-death-dr-alex-moore/ Quote Link to comment Share on other sites More sharing options...
