The artery and vein model shows a medium-sized muscular artery with two adjacent veins from the antebrachial area with adjoining fat tissue and muscle enlarged 14 times. The circulatory system model illustrates the reciprocal anatomical relationship of artery and vein and the basic functional techniques of the venous valves (“valve function� and “muscle pump�). The left vein and the middle artery are fenestrated in the upper anterior segment, revealing the various layers of the wall structure in a cross and longitudinal section and in top view. The right vein is opened throughout in the anterior segment, revealing the orifice of a feeder vein and two venous valves, i.e. “flap valves� formed by a duplication of the tunica intima. On the rear of the artery and vein model, the relief of two veins is shown to illustrate the functional aspect of the venous valves. A great tool for teaching about the human circulatory system. Artery and vein supplied on base.

This amazing working model of the human heart and circulatory system will bring your lecture to life! A complete schematic model of the human circulatory system with "blood" (colored water) that flows through transparent veins, arteries, capillaries and heart chambers. This model's special design portrays venous blood, a deep reddish purple and arterial blood, a bright red to give visual reinforcement to the oxygenation and deoxygenation of hemoglobin as it travels the body's vascular network. The functional heart and circulatory system are mounted on a baseboard with support legs and supplied with teacher's guide, red dye and syringe for refilling the system.

This resilient vinyl heart divides into anterior and posterior sections to access its pumping chambers and valves. Fitted with detachable/re-attachable bypass vessels for demonstrating single, double, and triple coronary bypass grafts, as well as normal heart without bypasses.

Vibrant handpainted colors permanently bond with the vinyl model, and are guaranteed not chip, crack, fade, peel or transfer. Vessels are color-coded red or blue to indicate whether they carry oxygenated or deoxygenated blood. Significant cardiac features, 33 in all, are hand numbered on the model for identification in the accompanying key.

Nesting on a form-fitting display base, the heart lifts off for hands-on observation and study. Overall dimensions: 4x4x6 inches (11x11x15cm).
