Vaso vasorum are defined as the small network of blood vessels present in large veins and arteries responsible for the blood supply and nourishment of large blood vessels.
There are three types of vaso vasorum including Vasa vasorum internae, Vasa vasorum externae, and Venous vasa vasorae. These three vessels together contribute for blood supply to the walls of large blood vessels like arteries and veins.
Arteries are having high pressure so the vasa vasorum serves for the outer layer of arteries and veins are having lower pressure which allows the vasa vasorum to get closer to the lumen and serves for nourishment of veins.
Hence, the given statement is true.
