Lab 2: Urinary System

A. Histology of Urinary System. Slide #6B (kidney)

Find glomerulus and Bowmans capsule together called the renalcorpuscle --- proximal convoluted tubule (lumen smaller due to largercells and microvilli which stain pink) --- distal convoluted tubule (moreopen lumen) --- collecting duct (very distinct, cuboidal cells withscalloped appearance) --- juxtaglomerular apparatus with ---uxtaglomerular cells --- and macula densa.
