Usage
- 1 power supply: AC 220V-50Hz, rated current:0.4A
- 2 power on and press “filter”: luminotrons connected to this press is light up, red and blue light source movement shows: blood move from afferent glomerular arteriole to Capillaries ball, then efferent arteriole and finally capillary network after the ball; meanwhile, yellow luminotron move to renal capsule, it demonstrates glomerular filtration, that is water and Small molecular substances in blood plasma are filtered by glomerulus and into renal capsule.
- 3 press “re-absorption”: luminotron connected to this press is light up, yellow luminotron’s movement demonstrates tubular fluid flows to collecting tubule.
- 4 press “continuous process”: luminotrons connected to this press is light up. Yellow luminotrons move to kidney tubules and red luminotrons move to blood capillary, this process demonstrates kidney tubules and collecting tubule’s re-absorption, Secretion and evacuation function. Those are three dynamic processes of urinary formation.
- 5 the speed of luminotrons can be controlled
