The body has a natural protection mechanism from bleeding to death and it is called clotting. In an injury situation fibrinogen molecules are converted to fibrin molecules which would collect at the site of injury and start collecting other blood components to essentially plug the leak.
Adequate circulation is important to help prevent and relieve muscle soreness that occurs from overexertion and the aging process. That is why antioxidants came to the forefront of wellness in the 90′s because of their ability to relieve oxidative stress. An overabundance of oxidative stress and free radicals in our system today has the same effect as an injury by initiating the clotting mechanism, converting fibrinogen molecules to fibrin. Fibrin molecules don’t necessarily become a full blood clot, but can be likened to tumbleweeds and in this case would float around in the blood and if they happened to land on a capillary opening they would essentially prevent blood flow down that branch. Kind of like hair in the shower drain slows the water from draining out fast enough.
