Vascular Response

Meaning

Vascular response refers to the dynamic and active changes in the diameter, permeability, and overall functional tone of the body’s blood vessels, primarily the arterioles and venules, in reaction to various physiological or pathological stimuli. This fundamental mechanism is absolutely critical for the precise regulation of systemic blood pressure, the targeted distribution of oxygen and nutrients, and the control of body temperature. Circulating hormones and local tissue factors precisely govern the vascular response to ensure appropriate tissue perfusion and maintain systemic hemodynamic stability.
