Microcirculation is the part of our circulatory system responsible for delivering not only essential oxygen to every cell in the body through regulated blood flow but also nutrients. At the same time, microcirculation is also responsible for removing metabolic waste products, such as carbon dioxide, resulting from cellular activity. As the term ‘micro’ suggests, it involves extremely small blood vessels, as cells are also very small (body cells are not visible to the naked eye). This means our body contains an extensive network of small blood vessels, some of which are 4 times thinner than a hair. Microcirculation consists of various structures: the smallest blood vessels (arterioles, capillaries, venules), initial (beginning) lymphatic vessels, and the interstitial space (space between blood vessels, lymphatic vessels, and cells).
