2. URINARY SYSTEM
Nephrogenic Kidneys
mesoderm
Urunary tract
Mesonephral
organs:
duct
Ureter
Urogenital Urinary bladder
sinus Urethra

3. Kidney
GENERAL CHARACTERISTICS
Type of structure – parenchymal lobulated
organs with
- cortex and
- medulla
Parenchyma – epithlium:
Epithlium forms:
- Nephrons
- Collecting duct system
Stroma – Connective tissue
- Capsule (DCT)
- narrow sheats of LCT (with
specialized system of vessels)

4. Renal vessels
Arteries/Veins:
- Renal
- Superior/inf
- arcuate
- interlobular
Arteriols
- afferent
- efferent
Capillaries:
-Primary - glomerular
- secondary - peritubular
FUNCIONAL signifacince:
- filtration (glomerular meswork)
- reabsorbtion (peritubular meswork)
-- nutrition of renal parenchyme

5. RENAL PARENCHYME
Includes 2 structures:
1. Nephrons
2. Collecting ducts
Nephron –is structural and
functional unit of kidney
Parts of nephron:
1. Renal corpuscule.
2. Tubules.
Types of nephrons :
1. Cortical (excretion)
2. Juxtamedullar
(concentration)
