reactive hyperaemia मीनिंग इन हिंदी

"' Reactive hyperaemia "'or "'venous hyperemia "'is the transient increase in organ blood flow that occurs following a brief period of shortage of oxygen and a build-up of metabolic waste.
Reactive hyperaemia often occurs as a consequence of Raynaud's phenomenon, where the vasospasm in the vasculature leads to ischaemia and necrosis of tissue and thus a subsequent increase in blood flow to remove the waste products and clear up cell debris.
