(Flecha verde) Podemos observar el endotelio que forma la túnica intima de este vaso arterial, conjuntamente el núcleo celular muy redondeado

(Flecha amarilla) Podemos observar las células musculares lisas, alargadas, que conforman la túnica media

(Flecha roja) Esta parte más externa de la estructura se puede aprecia la túnica adventicia formada por fibras de colágeno y fibras elásticas, por esta túnica adventicia también circula el vasa-vasorum que irriga a los vasos sanguíneos de gran calibre como la aorta, por ejemplo.

Por último y más divertido que en la luz (centro de imagen) podemos ver unos eritrocitos que circulan dentro de este vaso arterial

Ahora aquí les dejo el mismo vaso, pero en un corte longitudinal. No olvidemos que las arterias son estructuras tubulares.

¡Recuerda llevar una vida saludable y hacer ejercicio para mejora tu sistema circulatorio!

Have you ever wondered what your arteries look like under a microscope?
Well here we bring a little peek inside you.

In practice it is interesting to observe the microscopic structure of cells and the various tissues that make up the organism, always remembering that cells form tissue, tissues form organs and organs systems, it is very fun to observe that microscopic world that forms our organism, That is why today I bring you a very peculiar image under the microscope of an arterial vessel

The walls of the arteries are structured as follows: - Intimate tunic - Middle tunic - Tunica adventitia

(GREEN ARROW) We can see the endothelium that forms the tunica intima of this arterial vessel, together with the highly rounded cell nucleus.

(Yellow arrow) We can see the elongated smooth muscle cells that make up the tunica media

(Red arrow) In this most external part of the structure, the tunica adventitia can be seen, formed by collagen fibers and elastic fibers.

The vasa-vasorum also circulates through this tunica adventitia, which supplies blood vessels of great caliber such as the aorta, through example.

Lastly and more fun than in the light (image center) we can see some erythrocytes circulating within this arterial vessel.

Now here I leave the same glass, but in a longitudinal cut. Let's not forget that arteries are tubular structures.

Remember to lead a healthy life and exercise to improve your circulatory system!
