What is vascular dilation?
3 doctors weighed in across 2 answers
Relaxed blood vessel: Blood vessels are not pipes. They have muscles in the walls and are capable of expanding and contracting to maintain your blood pressure and volume. Vascular dilation or vasodilation refers to the state when blood vessels are relaxed and expanded such as when you drink alcohol or put a hot pack on your skin. Vasoconstriction is the opposite.
