Description

This detailed model of a vein showcases the intricate structure and function of the vascular system. The image highlights the vein’s three distinct layers: the tunica intima, tunica media, and tunica externa, each playing a crucial role in maintaining blood flow and vessel integrity. The depiction also emphasizes the presence of valves within the veins, which prevent blood from flowing backward, ensuring efficient circulation. This model is an excellent educational resource for students and healthcare professionals studying the circulatory system, vascular diseases, and the mechanisms behind conditions like varicose veins and deep vein thrombosis.
