Question: 1 / 580

Which medical term refers to the narrowing of blood vessels?

Vasodilation.

Vasoconstriction.

The term that refers to the narrowing of blood vessels is vasoconstriction. This process occurs when the muscles in the walls of the blood vessels contract, leading to a decrease in the diameter of the vessels. As a result, blood flow through these vessels is reduced, which can affect blood pressure and circulation.

Vasodilation, in contrast, describes the widening of blood vessels, which happens when those muscle walls relax, increasing blood flow. Hypertension refers to elevated blood pressure rather than the state of the blood vessels directly. An aneurysm is a condition that involves the abnormal enlargement or bulging of a blood vessel wall, not narrowing. Understanding these terms is essential in the context of cardiovascular health and the various conditions that can affect the circulatory system.
