Corte transversal de una arteria

La estructura de las paredes de los vasos sanguíneos es importante para la regulación del flujo sanguíneo. La túnica media contiene fibras musculares lisas que se contraen para dilatar o para constreñir el tamaño del vaso. Estos pequeños cambios en el lumen o luz del vaso pueden influir mucho en la presión sanguínea y en el flujo sanguíneo. Por lo tanto, la túnica media juega un papel importante en el mantenimiento de la presión sanguínea y de la continuidad de la circulación sanguínea.
