    GlossaryVasodilation

    widening of blood vessels due to muscle relaxation

    Vasodilation is the process by which blood vessels widen or dilate, usually as a result of relaxation of the muscular walls of the vessels. This increases blood flow and decreases blood pressure, and can be triggered by various factors such as heat, low oxygen levels, or certain medications. For professionals, it's important to note that vasodilation plays a critical role in thermoregulation and the delivery of oxygen and nutrients to tissues.
