This amazing working model will bring your lecture to life! A complete schematic model of the human circulatory system with “blood” (coloured 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 haemoglobin as it travels the body's vascular network.
Mounted on a baseboard with support legs and supplied with teacher’s guide, red dye and syringe for refilling the system. Size: 36 x 16 x 38 cm
