The Urinary System:
General structure of the kidney
o Bean shaped organ in abdominal cavity
o Covered by a connective tissue capsule
o Medial border concave contains a hilus through which renal
vessels/nerves pass and origin of ureter leaves
o Divided into outer cortex and inner medulla
o Medulla
8-12 conical structures pyramids
Bases of pyramid face capsule, apices face hilus
Pyramids consist of numerous tubules and vessels which
converge from the base to apex
Tissue between pyramids renal column continuous
with cortex
o Cortex
Multiple straight and convoluted tubules, blood vessels and
renal corpuscles
Pyramid with is overlying cortical tissue and neighboring
tissue in renal columns lobe of kidney
Lobes of kidney further subdivided into lobules consists
of cortical material between 2 interlobular arteries
o Renal pelvis
Expanded origin of the ureter
Divides into major calyces
Major calyces further subdivide into minor calyces
collect urine from the apex of a pyramid
Portion of the pyramidal apex that projects into minor calyx
papilla
Nephron
o Functional unit of the kidney
o Consists of
Nephron renal corpuscle + convoluted and straight
tubules
Renal corpuscle Bowman’s capsule + glomerulus
Glomerulus tuft of capillaries contained in Bowman’s
capsule
Renal Corpuscle
o Filtration apparatus of kidney
o Produces ~180L of plasma filtrate per day
o Consists of a tuft of capillaries (glomerulus) sitting inside a double
walled epithelial capsule Bowman’s capsule
o Blood enters via afferent arterioles and leaves via efferent
arterioles
o )nner layer of Bowman’s capsule envelops capillaries of
glomerulus visceral epithelium
o Outer layer forms wall of capsule parietal epithelium
o Both layers are made of simple squamous epithelium
