The arteries
The artery wall is generally made up of three Tunics casings:
1- Tunica intima
It consists of an endothelium layer and an endothelium and subendothelium layer composed of a fine rubber fibrous tissue followed by a membrane made of elastic fibers called the internal elastic membrane.
2- Tunica media
It consists mainly of smooth muscle cells arranged in a circular way.
3- Tunica adventitia
It consists mainly of a link fabric, most of whose elements take a position parallel to the longitudinal axis of the vessel. This layer separates from the middle layer or tunic a membrane called the external elastic membrane.
The arterial blood vessels are classified into three groups:
Arterioles are the smallest arterial blood vessels.
Small and medium sized arteries contain many muscle components.
Large arteries
It contains a large amount of soft fibers (such as Aorta and its main branches).
