This excretory organs model gives your students complete access – from the front, back, right, and left Typically models of the urinary system are in reality nothing more than 2-dimensional relief plaques – which offer no encouragement towards hands on investigation – and which present only half the picture. But this larger than life replica is free standing, fully three dimensional, and totally approachable from all sides. Your students really can, and will get their hands on it. Overall dimensions on wooden base: 12 x 9 x 8 inches (30 x 48 x 20 cm)
