Renal Stroma
capsule consists of __ layers

Describe layers

-dense irregular CT
-collagen fibers

Renal Stroma
Internal stroma
2 layers
-Reticular fibers are numerous
-uriniferous tubule epithelium has a basal lamina
supported by
-reticular fibers.

Collagenous fibers in varying degrees
-some fibroblasts
-macrophages are present

-Less stroma in cortex
compared to medulla

cortex (subdivided into =
outer cortex
juxtamedullary cortex

subdivided into
outer medulla
inner medulla
Vertical striations emanating from medulla are seen in cortex. These are called
Vertical striations emanating from medulla are seen in cortex. These are called

medullary rays.

Medullary rays contain =
medullary rays.

Medullary rays contain =
-straight tubules
-collecting ducts.
The region between the medullary rays contain the =
-renal corpuscles
-convoluted tubules of nephrons and
-collecting tubules.

These areas are referred to as the =
cortical labyrinth.
The medulla is characterized by
-straight tubules of the nephrons,
-collecting ducts
and a special capillary network called =
vasa recta.

Vasa recta runs parallel to tubules and participate in =
-countercurrent exchange system

that regulates the concentration of the urine.
The tubules form =
conical structures called =
The bases of pyramids face =

and the
apices face the =
Renal sinus.
Each pyramid is divided into an =
an outer medulla (adjacent to cortex) and an inner medulla.

The outer medulla is further subdivided into an
-outer stripe

-inner stripe.
The renal columns represents
-cortical tissue
contained within =
Lobes and lobules

medullary pyramid, together with the associated covering =
-cortical region,
constitutes a =

The base of the renal lobe is the =
-renal lobe.

-renal capsule.
The lateral boundaries of each renal lobe are the =
renal columns (of Bertin),
renal columns (of Bertin),
The lateral boundaries of each renal lobe
renal columns (of Bertin),
residual structures representing the fusion of primitive lobes within the =
metanephric blastema.
The apex of each renal lobe terminates in a conic-shaped papilla surfaced by the area =
(the opening site of the papillary ducts).
papilla is surrounded by a
minor calyx.
Each minor calyx collects the urine from a papilla dripping from the
area cribrosa.
Minor calyces converge to form the =
major calyces

which, in turn, form the =
renal pelvis
The renal lobule is a portion of the cortex flanked by two adjacent =
ascending interlobular arteries.

A medullary ray is the =
axis of the lobule
Each kidney has about _________ ct uriniferous tubules =
1.3 million

surrounded by a stroma containing loose = 4ct
-blood vessels
Each uriniferous tubule consists of two embryologically distinct segments:
= 2ct
collecting duct
structural and functional unit of kidney
nephron is considered =
structural and functional unit of kidney
nephron consists of two components:
renal corpuscle (300 μm in diameter)
long renal tubule (5 to 7 mm long).
renal tubule consists of several regions: =
-proximal convoluted tubule
-loop of Henle
-distal convoluted tubule,
which empties into the
-collecting tubule.
Depending on the distribution of renal corpuscles,
nephrons can be either =
Renal tubules derived from cortical nephrons have a =
short loop of Henle

that penetrates just up to the =
outer medulla.
Renal tubules from juxtamedullary nephrons have a =
-long loop of Henle
projecting into the =
inner medulla,
