Lab 2: Urinary System
 
A. Histology of Urinary System
1. Slide #6B (kidney)
Find – glomerulus and Bowman’s capsule together called the renal corpuscle --- proximal convoluted tubule (lumen smaller due to larger cells and microvilli which stain pink) --- distal convoluted tubule (more open lumen) --- collecting duct (very distinct, cuboidal cells with scalloped appearance) --- juxtaglomerular apparatus with --- juxtaglomerular cells --- and macula densa.
 
2. Slide #7B (ureter)
Find – transitional epithelium --- mucosa --- lamina propria --- tunica muscularis --- (longitudinal and circular layers) --- adventitia.
 
B. Models of Urinary System
 
1. Larger kidney model
  Videos: Blood Circulation; Cortex & Medulla
Find – renal cortex --- renal medulla --- renal pyramid --- renal column --- renal papilla --- minor calyx --- major calyx --- renal pelvis --- renal capsule --- renal artery --- renal vein --- renal sinus (with adipose tissue) --- segmental artery and vein --- interlobar artery and vein --- arcuate artery and vein --- interlobular artery and vein --- hilus --- ureter.
 
2. Triangular section of kidney model
  Videos: Cortex & Medulla; Juxtaglomerular Nephron; Cortical Nephron
Find renal cortex --- renal medulla --- renal corpuscle --- glomerular (Bowmans) capsule --- nephron --- proximal convoluted tubule --- distal convoluted tubule --- loop of Henle --- connecting tubule --- collecting duct --- papillary duct --- interlobar artery and vein --- arcuate artery and vein --- interlobular artery and vein --- afferent and efferent arterioles --- vasa recta --- pyramids.
 
3. Renal corpuscle model with removable glomerulus
  Videos: Tubular & Vascular Poles; Renal Capsule 
Find – glomerular (Bowman’s) capsule with parietal and visceral layer --- glomerulus --- podocytes with pedicels and filtration slits (visceral layer of glomerular capsule) --- proximal convoluted tubule with microvilli --- capsular space --- juxtaglomerular apparatus --- juxtaglomerular cells --- macula densa --- efferent arteriole --- afferent arteriole.
 
C. Preserved Human and Pork Kidneys
Find – renal capsule --- renal cortex --- renal medulla --- renal column --- minor calyx --- renal pyramid --- renal papilla --- minor calyx --- renal pelvis --- adipose tissue --- ureter --- hilus.
