Glossary Vasoconstriction

narrowing of blood vessels due to muscle contraction

Vasoconstriction is the narrowing of blood vessels due to the contraction of the muscular wall of the vessels, particularly the large arteries and small arterioles. This process reduces blood flow to certain areas of the body, which can help conserve heat or redirect blood to essential organs. For professionals, it's important to note that vasoconstriction is regulated by the autonomic nervous system and can be influenced by various factors, including temperature, stress, and certain medications.
