Arteries are blood vessels within the body that provide oxygen-rich blood to the tissues in the body, as defined by WebMD. The arteries are able to deliver this oxygen due to the pumping mechanism of the heart.
The function of the arteries is to carry oxygenated blood to organs and cells in the body. Because of this, arterial blood has a bright red color and flows away from the heart.
Arteries have three main layers or tunics known as the adventitia (outer), media (middle) and intima (inner). The outer layer is made of connective tissue with collagen fibers, the middle layer consists of smooth muscle and elastic fibers, and the innermost layer is composed of specialized squamous
