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)

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

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)
