Vascular Homeostasis Flow Art

Vascular homeostasis maintains flow via autoregulation myogenic metabolic matching perfusion demand, endothelial nitric oxide prostacyclin vasodilation shear stress, endothelin angiotensin constriction, arteriolar tone dominant resistance site, capillary hydrostatic oncotic pressures Starling forces fluid balance, baroreceptors long-term renin angiotensin aldosterone volume control ensuring tissue oxygenation despite posture activity changes.
