The following Terms and Concepts are important in the study of the Urinary System:
| Gross anatomy of Kidney:
Kidney Ureter urinary bladder urethra renal artery renal vein renal hilum
Internal anatomy of Kidney: Renal cortex renal medulla calyces (minor, major) renal pyramids renal columns renal papillae renal pelvis
Anatomy of the Nephron: Nephron Renal corpuscle (glomerulus, bowman’s capsule), afferent arteriole efferent arteriole proximal convoluted tubule (PCT) distal convoluted tubule (DCT) loops of Henle (descending and ascending) collecting ducts |
Filtrate production:
Fenestrations Filtration slits Forming urine Net filtration pressure Glomerular filtration rate (GFR)
Urine Concentration: countercurrent multiplier system aquaporin
Alteration of Filtrate Production and Urine Contents: Direct: myogenic mechanism, tubuloglomerular feedback via juxtaglomerular apparatus (JGA) and macula densa cells
Hormonal: angiotensinogen, angiotensin I and II, renin
