Key benefits Realistic teaching tool: depicts a mediumstrength muscular artery in the upper arm with two adjacent veins and surrounding adipose tissue and muscle, illustrating the anatomical relationship between arteries and veins. Venous valve function demonstrated: shows valve action and muscle pump to help learners understand venous physiology. Durable and safe: made of quality PVC material, sturdy and safe to use. Clear, durable coloring: bright colors created with computer color matching, easy to distinguish different components and resist fading. Enhanced detail: the venous artery is magnified 14 times with delicate texture and detail; the front part of the right vein is fully opened to reveal the venous inlet and two venous valves, including a vertical valve formed by a pair of intima, providing realistic observation and learning value. Product features Material: PVC Size: 32x18x33 cm (12.6x7x13 in) Model scope: upper arm, includes a mediumstrength muscular artery, two adjacent veins, and surrounding adipose tissue and muscle Color design: computerassisted color matching for clear differentiation and durability Simulation level: 14x magnification of the venous artery, with detailed textures and structures Special observation point: front part of the right vein completely opened to show venous inlet and two venous valves; vertical valve composed of a pair of intima What it helps you do Observe and learn the spatial relationship between arteries and veins in the upper arm. Learn the basic functional skills of the venous valve and the muscle pump mechanism. Practice identifying components and understanding their relationships in a realistic vascular model. Use scenarios Classroom demonstrations in biology or anatomy courses to teach upperarm vascular anatomy. Selfstudy or tutoring sessions focused on venous valves and muscle pump mechanics. Laboratory exercises in medical or physiotherapy training to explore arterialvenous relationships and tissue context.
