Vasodilation occurs when the smooth muscles in our blood vessels relax and cause the interior of the blood vessels, called the lumen[1], to become wider in diameter. Due to the increase in space within each vessel, there is less vascular resistance resulting in a much greater rate of blood flow[2].
Also due to the cardiac output remaining constant but a greater volume of space available, the blood pressure decreases.
