These 3 kidney models create a complete series to study the anatomy of the kidney and the different structures of the kidney in great detail. Together the human kidney models show: A longitudinal section of the right kidney, 3 times life-size A kidney nephron depicting a section through renal cortex and medulla. Nephron features the renal corpuscles with proximal and distal convoluted tubules, loops of Henle, collecting tubules and blood vessels, 120 times full-size The third kidney section shows an opened Malpighian corpuscle with glomerulus and Bowman's capsule, 700 times life-size of the human kidney. The 3 kidney models are mounted on one baseboard for easy display during an anatomy lesson or demonstration about the human kidney. This high quality model is a great addition for any classroom!
