There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart. Theyâre tough on the outside but they contain a smooth interior layer of epithelial cells that allows blood to flow easily.
Arteries are brighter red and narrower than veins. Actually, the retinal arteries lack a muscular coat, so they are more correctly called arterioles. The vessels you see here supply and drain the inner retina, including the retinal ganglion cells and their axons and the bipolar cells.he retinal arteries and veins emerge from the nasal side (left) of the optic disc. Vessels directed temporally have an arching course; those directed nasally have a radial course.
