Arteries, part of your circulatory (cardiovascular) system, are the blood vessels that bring oxygen-rich blood from your heart to all of your body’s cells. They play a crucial role in distributing oxygen, nutrients and hormones throughout your body. Arteries keep your body alive and healthy by delivering what your cells and tissues need.

Figure 17.4.2 17.4. 2: This figure shows the heart and the major arteries of the cardiovascular system. The pulmonary veins are included in the diagram because, like ...
The arteries throughout the body are composed of three different layers. The most inner layer is the tunica intima: Made up of a smooth muscle layer that contains one layer of endothelial cells, and the rest is smooth muscle and elastin; creates a tube for the oxygen-rich blood to move through to reach the appropriate site of perfusion ( ensuring there is no leakage from the artery, and the ...
