The walls of arteries and veins have three layers or tunics: An outer layer (tunica adventitia) of connective tissue with collagen fibers. An inner layer (tunica intima), consisting of a specialized simple squamous epithelium, often called the endothelium, that lines all blood vessels and the endocardium of the heart.

The blood pressure on veins is less than that in the arteries because they are draining blood from the capillary bed. As a consequence of lower pressure in veins, they contain internal flaps which act as one way valves to prevent blood from flowing in the wrong direction. Veins return blood to the heart.

The three layers of tissue in arteries and veins are:

The inner layer: the tunica intima.

The middle layer: the tunica media.

The outer layer: the tunica externa.

What are arteries and veins?

Arteries and veins are the small, thin tubes that are present in our whole body. They carry blood from hearts and transport it to the different body parts. They come under the circulatory system.

There are three layers of artery and veins: the inner layer is a specialized, simple squamous epithelium that coats all blood arteries and the endocardium of the heart. The middle layer and the outer layer consist of connective tissue and collagen fibers.

The functions of the structure of arteries and veins are arteries carry blood under high pressure and veins carry blood under low pressure.

Thus, the three layers are the tunica intima, the tunica media, and the tunica externa.
