Question
Chapter 22, Problem 3RC
Summary Introduction
Introduction:
Artery and vein walls are divided into three layers, which are the outer adventitia, the middle media, and the inner intima. The inner intima layer of the blood vessels is made up of the endothelial cells. It forms an endothelial lining, below which lies the connective tissue layer.
