PATHOLOGY

Detailed explanation-1: -Vasoconstriction is an immediate response to cutaneous injury acting in concert with platelet aggregation to reduce blood loss.

Detailed explanation-2: -Vasoconstriction reduces the volume or space inside affected blood vessels. When blood vessel volume is lowered, blood flow is also reduced. At the same time, the resistance or force of blood flow is raised. This causes higher blood pressure.

Detailed explanation-3: -Vasoconstriction is the narrowing (constriction) of blood vessels by small muscles in their walls. When blood vessels constrict, blood flow is slowed or blocked. Vasoconstriction may be slight or severe. It may result from disease, drugs, or psychological conditions.

Detailed explanation-4: -Acute Inflammation Immediately following an injury, vasoconstriction of blood vessels will occur to minimize blood loss. The amount of vasoconstriction is related to the amount of vascular injury, but it is usually brief.
