Improve Circulation

Hi Michael,
Glad to! The microcirculation, consisting of resistance arteries, arterioles, capillaries, and venules, has been the focus of increasing research interest in recent years. Previously, many of the most important forms of cardiovascular disease were considered to involve primarily large vessels, particularly the conduit arteries. However, recent advances have highlighted the crucial involvement of the microcirculation in many cardiovascular conditions. Hypertension predisposes to all major forms of cardiovascular disease, and it has long been recognized that distinctive changes in the structure of small vessels, such as an increase in media:lumen ratio, and changes at the microvascular network level, such as arteriolar and capillary rarefaction, accompany many forms of hypertension in humans and animals. Closer attention to the microcirculation will ultimately improve the treatment and prevention of many of the most important forms of cardiovascular diseases. Carbon dioxide (CO2) is one of the mediators of local autoregulation of blood supply. If its levels are high, the capillaries expand to allow a greater blood flow to that tissue.
