Microcirculation consists of arterioles, capillaries, and venules. ... The most important function of the microcirculation during the inflammatory response is to ensure rapid and abundant delivery of leukocytes to the inflamed tissue site.
Microcirculation is the smallest blood vessels in the circulation of blood, and the microvascularization of microvessels present in organic tissue. Microvessels include terminal arterioles, metarterioles, capillaries and venules. The arterioles transport oxygenated blood to the capillaries and blood flows through the capillaries into the venules.
In addition to these blood vessels, the microcirculation also includes lymphatic capillaries and collecting ducts. The main functions of microcirculation are the supply of oxygen and nutrients and the elimination of carbon dioxide (CO2). It is also used to regulate blood flow and tissue perfusion, thereby affecting blood pressure and inflammation responses which may include edema (swelling). Most vessels in the microcirculation are lined with flattened cells of the endothelium, and many of them are surrounded by contractile cells called pericytes. The endothelium provides a smooth surface In addition to these blood vessels, the microcirculation also includes lymphatic capillaries and collecting ducts. The main functions of the microcirculation are the delivery of oxygen and nutrients and the removal of carbon dioxide (CO2). It also serves to regulate blood flow and tissue perfusion thereby affecting blood pressure and responses to inflammation which can include edema (swelling).
