Manufacturer Description:

The 3B MICROanatomy Kidney is an extremely detailed model which shows the morphologic/functional units of the kidney. The kidney structures are greatly magnified. Six model zones illustrate the following fine-tissue structures of the human kidney that serve in the production of urine:

  • Longitudinal section of a kidney

  • Section of renal cortex and renal medulla of the kidney

  • Wedge-shaped section of a kidney lobe with a diagrammatic depiction of three nephrons with Henle's loops of different lengths and diagrammatic depiction of the vascular supply

  • Diagrammatic illustration of a kidney nephron with a short Henle's loop and didactic/diagrammatic illustration of the vascular supply

  • Diagrammatic illustration of an opened kidney renal corpuscle with nephron and light-microscopic transverse sections of the proximal, attenuated and distal segments of a renal tubule

  • Diagrammatic/didactic illustration of an opened kidney renal corpuscle

3B MICROanatomy Kidney mounted on a base.

Video Transcription

Here’s another renal corpuscle model but we’re going to see a lot more features of the urinary system on this total model. Again, efferent arteriole bringing blood in to the glomerulus, the blood is filtered into a filtrate which will leave through the proximal convoluted tubule and the blood that did not get filtered into this space leaves through the efferent arteriole. Everything comes back. The distal convoluted tubule is here and the macula densa cells are around there with some juxtaglomerular cells here. As we look at the different side of that, here’s our renal corpuscle and the proximal convoluted tubule is leaving in yellow heading in to the Loop of Henle which is here, so we’ve got our descending limb and then the ascending limb of the Loop of Henle in white. The ascending limb turns into the distal convoluted tubule and part of that comes back over here so this is our macula densa and then flipping the model around, we can see multiple renal corpuscles, multiple proximal convoluted tubules and distal convoluted tubules and Loops of Henle. Here’s an example of just a cortical nephron. Here is the juxtamedullary nephron and an even deeper juxtamedullary nephron. After the distal convoluted tubule, the filtrate which is now going to be urine goes into the collecting duct. This is a collecting duct which is going down the renal pyramid, this shape right here and then off to the side of the renal pyramid is the renal column. Also on this side, the efferent arteriole is going to come down and provide this capillary bed around the Loop of Henle which is the vasa recta. If we took a look at the other side of the model, here’s the renal pyramid in this darker pink color and the renal column separates renal pyramids. The collecting ducts are going to merge together and drain into a minor calyx which is at the tip of the pyramid and minor calyces will join into major calyces, it’s about 2 to 3 major calyces per kidney and then the major calyces will drain into 1 renal pelvis which then drains into the ureter on its way to the urinary bladder.
