vasodilaatioon
Vasodilaatio is a physiological process where blood vessels widen. This widening, or dilation, increases the diameter of the lumen, the inner space of the blood vessel, which in turn reduces resistance to blood flow. Consequently, blood pressure tends to decrease. Vasodilaatio is the opposite of vasoconstriction, where blood vessels narrow. This process is crucial for regulating blood flow to various parts of the body and maintaining cardiovascular homeostasis.
Several factors can trigger vasodilaatio. These include mechanical stimuli like increased shear stress on the vessel
Vasodilaatio is vital for thermoregulation, allowing the body to dissipate heat by increasing blood flow to
