Urine Formation Dynamic Model, Electric Biological Teaching Model with LED Light, 3D Dynamic Demonstration, Adjustable Speed, Suitable for Science Classroom Lea

[Working principle]: This model adopts the principle of integrated circuits, and displays glomerular filtration and tubular reabsorption through light-emitting tubes [Dynamic model of urine generation]: This model can intuitively reflect the structure of the renal unit: renal corpuscle: glomerulus, renal capsule; renal tubule: proximal convoluted tubule, medullary segment, distal convoluted tubule [LED light]: The directional flow of blood and urine is displayed through light-emitting tubes, where blood is displayed with red light-emitting tubes and urine is displayed with light yellow light-emitting tubes [Teaching demonstration]: The dynamic demonstration button can adjust the speed, with richer information and more interesting teaching, which helps to improve students' learning effect [Material]: The exterior adopts a basic frame, a transparent plastic panel, and aluminum alloy corners, and the internal insulating plastic board is used to fix the circuit board, which is safe and durable, Manufacturer: GUHPZA
