Kidney
ØSize: about 11cm long

Kidney
A layer of connective tissue that surrounds each kidney.
Renal capsule
Layers of connective tissues
Renal fascia
Perirenal fat capsule
Fibrous capsule
anchors the kidney
Renal fascia
Fatty cushion
Perirenal fat capsule
Adheres to kidney and prevent spread of infection
Fibrous capsule
where renal artery and nerves enter and renal vein, ureter and lymph vessels exit the kidney
Renal hilum
outer surface of the kidney
Renal cortex
inner surface which surround the renal sinus
Renal medulla
coned shape tissue masses located in the renal medulla
Renal pyramids
funnel-shaped structure which surround the tip of renal pyramid.
Renal calyces
The calyces from all the renal pyramids join to form a larger
funnel called
Renal pelvis
Functional
unit of kidney.
Nephron
This is where urine
production/formation
happens
Nephron
Extends from renal
cortex to calyces
Nephron
Parts of nephron
Renal corpuscle
Renal tubules
Classes of nephrons
Cortical
Juxtamedullary
accounts for
the 85% of the
nephrons
Cortical
accounts for 15% of
the nephrons
Juxtamedullary
Urine produced by three processes
- Filtration
- Tubular Reabsorption
- Tubular Secretion
Divided into right and left.
Ureters
Small tubes that carry urine
from renal pelvis of the
kidney to the posterior
portion of the urinary
bladder
Ureters
A hollow muscular
container that lies
in the pelvic cavity
just posterior to the
pubic symphysis.
