PATHOLOGY

Detailed explanation-1: -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-2: -Vasoconstriction may also be called vasospasm. It is a normal process that helps keep your body in healthy balance. Vasoconstriction may occur to: stabilize blood pressure or raise blood pressure.

Detailed explanation-3: -Blood vessels also contain muscle, and that muscle controls just how wide or narrow your blood vessels are at any given time. When blood vessels get wider, that’s vasodilation. The opposite process, when blood vessels constrict and get narrower, is called vasoconstriction.

Detailed explanation-4: -Vasoconstriction is the narrowing of blood vessels, typically when the muscles of blood vessel walls become constricted, causing the vessel lumen to become smaller. Vasoconstriction can be a reaction to cold, stress, cigarette smoking, medications, or underlying medical conditions, such as the Raynaud phenomenon.

Detailed explanation-5: -Medications causing vasoconstriction, also known as vasoconstrictors, are one type of medicine used to raise blood pressure. Generalized vasoconstriction usually results in an increase in systemic blood pressure, but it may also occur in specific tissues, causing a localized reduction in blood flow.
