vasoconstrikcióból
Vasoconstriction is the narrowing of blood vessels. This process occurs when the smooth muscle in the wall of a blood vessel contracts, reducing the diameter of the lumen. Vasoconstriction is a crucial physiological mechanism that plays a significant role in regulating blood pressure, controlling blood flow to specific organs, and preventing blood loss.
Several factors can trigger vasoconstriction. Hormones such as epinephrine (adrenaline) and norepinephrine (noradrenaline) are potent vasoconstrictors,
The physiological consequences of vasoconstriction include an increase in peripheral vascular resistance, which can elevate blood
