This highly detailed 3D anatomical model illustrates the structural differences between arteries and veins, including a connecting capillary network. It features labeled internal and external layers such as the endothelium, subendothelial layer, internal and external elastic membranes, smooth muscle, and additional vein-specific structures like valves. The model is ideal for medical students, educators, or healthcare professionals seeking a clear, visual representation of blood vessel anatomy. Designed for 3D printing, it is an educational tool to demonstrate blood flow pathways and vessel wall composition in a tangible format.
