WebIf perfusion of an organ is too low (ischemia), the tissue will experience low levels of oxygen (hypoxia). In contrast, excessive perfusion could damage the organ’s smaller and more fragile vessels. The myogenic response is a localized process that serves to stabilize blood flow in the capillary network that follows that arteriole. WebMicrovascular rarefaction is constantly observed in hypertension, and probably contributes to higher systemic resistance and lower tissue perfusion. Endothelial dysfunction leading to impaired arteriolar reactivity is also characteristic of the microvascular dysfunction in hypertensive patients. how many gb in 10 tb https://gpstechnologysolutions.com
