Perirneal
Pararenal
Perineal fat is found
Inside the renal fascia
Pararenal fat is found
Outside the renal fascia
What are kidneys?
Retroperitoneal glands invested in a fibro-fatty layer composed of 2 layers of fat and a membrane
What is the membrane of the kidney?
Renal fascia (Gerota’s fascia)
What are the 2 surfaces of the kidney
Anterior and posterior
What are the 2 borders of the kidney?
Lateral and medial
What are the 2 ples of the kidney?
Superior and inferior
Do the suprarenal glands touch they kidneys?
No
They are separated from the kidneys by the perirenal fat capsule
What organs come into contact with the kidneys?

Spleen
Pancreas
Descending colon
What 4 segements are kidneys divided into?
Anterior
Posterior
Apical
Basilar
Medulla of kidney divides into
Medullary pyrmaids with renal columns made of cortical tissue between them
Renal pyramids have __ that point toward the center of the kidney
Renal papilla
Renal tubules dump into ___ that then join to form ___ and then into ___
Dump into minor calices and then join to form major calices and then into the renal pelvis
Renal columns (function)
Separate renal pyramids from each other
Renal pyramids (function)
Come together to form the renal papilla
Renal papilla are located
The apex of the renal pyramid
Minor calyces are
The beginning of the extrarenal duct system
They are cup-shaped structures that receive renal papillae
Major calyces (function)
Receive minor calyces which drain urine from superior, middle, and inferior portions of the kidney
Renal pelvis (function)
Flattened funnel-shaped expansion of the superior end of the ureter
The apex of the renal pelvis is continuous with
the ureter
Renal arteries (structure)
Single vessels that extend from the aorta that branch into several segmental arteries before entering the renal sinus
Right renal artery runs posterior to
IVC
Left renal artery runs posterior to
Left renal vein
Interlobar arteries
Pass through renal columns to supply each pyramid
Arcuate arteries are
branches of interlobar arteries that supply each pyramid
Interlobular arteries are branches of
Arcuate artery that become the afferent arterioles
The left renal vein is anterior to___ and posterior to ___
Anterior to aorta and left renal artery
Posterior to SMA
The renal veins eventually drain into the
IVC
The left renal vein is in continuity with
Left gonadal vein
Left inferior adrenal vein
Lumbar vein
Left adrenal vein enters ___ while the left gonadal vein enters ___
Adrenal enters superiorly
Gonadal enters inferiorly
What are the 3 stages in kidney embryology?
Pronephros
Mesonephros
