3B MICROanatomy Kidney Model

The 3B MICROanatomy Kidney is a highly detailed model that shows the morphologic and 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

The 3B MICROanatomy Kidney is mounted on a base, making it easy to display and study.

Video Transcription

Here's another renal corpuscle model, but this one shows more features of the urinary system. The efferent arteriole brings blood into the glomerulus, where it is filtered into a filtrate that leaves through the proximal convoluted tubule. Blood that is not filtered leaves through the efferent arteriole. The distal convoluted tubule and macula densa cells are also visible, along with juxtaglomerular cells. The model shows the renal corpuscle, proximal convoluted tubule, and the Loop of Henle, including its descending and ascending limbs. The ascending limb turns into the distal convoluted tubule, which connects to the macula densa. The model also displays multiple renal corpuscles, proximal and distal convoluted tubules, and Loops of Henle. It includes examples of cortical and juxtamedullary nephrons. After the distal convoluted tubule, the filtrate, now urine, goes into the collecting duct, which travels down the renal pyramid and into the renal column. The efferent arteriole provides a capillary bed around the Loop of Henle, known as the vasa recta. The renal pyramid and column are also shown, with collecting ducts merging into minor calyces, which join into major calyces, and then drain into the renal pelvis and ureter, leading to the urinary bladder.
