Kidneys – urine production endocrine
Ureters – voiding of urine Urinary bladder–urine deposition
Urethra – voiding of urine
• Embryogenesis of urinary system
• Source – intermediate mesoderm (nephrogonotom)
• Stages – pronephroi
mesonephroi
metanephroi

MFU – nephronrenal corpuscle+tubular system
Types: 1. cortical – short and long2. juxtamedullary
Blood supply
1. 25% of cardiac output
2. Two capillary systems (glomerular and peritubular)
3. High blood pressure in glomerulus

Glomerular filter
Between circulating blood and urinary space
• Podocyte
• Basement membrane unusialy thick physical and electrical barrier
• Endothelium fenestrated
