This 3D model of a 4-piece vein cross-section provides a highly detailed and anatomically accurate representation of vein structure and function. It illustrates the layered composition of veins, including the tunica intima, tunica media, and tunica externa, along with venous valves that prevent the backflow of blood. The model effectively demonstrates the differences in vein wall thickness and elasticity compared to arteries, highlighting their role in returning deoxygenated blood to the heart.

Designed for educational and clinical purposes, this 4-piece model allows for a step-by-step exploration of vein anatomy, making it ideal for studying vascular structure, blood flow dynamics, and conditions such as varicose veins, thrombosis, and venous insufficiency. It is perfect for medical professionals, educators, and students, providing a hands-on approach to teaching, training, and patient education about the circulatory system and vascular health.
