Urinary system model 0827-45

kidneybladderblood vessels

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. Both kidneys, with their respective adrenal glands, major blood vessels, ureters and the upper half of the bladder - opened to reveal its interior - are included. Blood vessels are color coded - red for arteries - blue veins. One kidney has been sectioned open along its full length to exhibit its network of filtration and collection tubules. Ureters are made of flexible transparent plastic tubing. 41 major features are numbered on the model for identification in the accompanying printed key.
