Description

This detailed anatomical illustration depicts the structure of an elastic artery wall, highlighting its key layers and functional components. The image showcases the thick tunica media, rich in elastic fibers, which allows these arteries to expand and recoil with each heartbeat, maintaining continuous blood flow. The tunica intima, lined with endothelial cells, ensures smooth blood circulation, while the tunica externa provides structural support. Found in large arteries such as the aorta and pulmonary arteries, this specialized wall composition plays a crucial role in dampening pulse pressure and ensuring efficient blood distribution. This visual serves as a valuable educational tool for understanding vascular physiology and arterial biomechanics.
