Renal capsule Outer layer of kidney
Renal cortex Superficial reddish area
Renal medulla Deep darker area containing the pyramids and columns
Renal column Area between the pyramids
Renal pyramid 2 3 1 4 5 6 7
Minor calyx Each kidney contains 8-18
Major calyx Each kidney contains 2-3
trigone Contains the 2 ureteral openings
Prostatic urethra Portion of the urethra that passes through the prostate
Membranous urethra Intermediate and shortest section of the male urethra
Penile urethra Portion of the urethra that passes through the penis
Internal urethral sphincter
External urethral sphincter
RENAL BLOOD SUPPLY
Segmental artery Renal artery divides and each segmental artery supplies one renal region
Interlobar artery Blood vessels that pass through the columns between the pyramids
Arcuate artery Blood vessels that form an arc between the cortex and the medulla
Interlobular artery Branch from arcuate arteries to enter the cortex
Afferent arteriole Branches from interlobular arteries and is where blood enters glomerulus
Efferent arteriole Blood exits glomerulus
Peritubular capillariesefferent arterioles divide to surround portions of the nephron in the cortex
Vasa recta Some efferent arterioles have long loop-shaped capillaries that surround portions of the nephron in the medulla
Interlobular vein Peritubular capillaries reunite to form interlobular veins Interlobular veins also receive blood from the vasa recta
Arcuate vein Receives blood from the interlobular veins
Interlobar vein Pass through the renal columns and receives blood from arcuate veins
Segmental vein Receives blood from the interlobar veins
Nephron Contains one renal corpuscle and its renal tubule
Renal corpuscle Lies in the cortex and contains GlomerulusBowman’s Capsule
Glomerular (Bowman’s) capsuleDouble walled epithelial cup that surrounds the glomerulus
Visceral layer of Bowman’s capsuleNucleus of podocyte
Proximal convoluted tubule (PCT)(orange twisted) Portion of renal tubule that lies in the cortex and is attached to the glomerulus and coiled
Loop of Henle Also called a nephron loopExtends into the medulla, makes a hairpin turn, and returns to the cortex
Descending limb (orange straight) Portion of the nephron loop that descends from the PCT into the medulla
Ascending limb (purple straight) Portion of the nephron loop that ascends from medulla and returns to the cortex, attaching to the DCT
Distal convoluted tubule (DCT)(purple twisted) Portion of renal tubule that lies in the cortex and is attached to the collecting duct and coiled
Collecting tubule (duct)Several DCTs drain into one collecting duct
Juxtaglomerular apparatus (JGA)Distant Convoluted Tubule Afferent arteriole Regulates arterial blood pressure and the rate of blood filtration by the kidneys
Macula densa Tall crowded cells on the wall of the distal convoluted tubule that monitor ion concentration of the fluid passing through
Juxtaglomerular cellsIn the wall of the afferent arteriole These are modified smooth muscle fibers
Types of nephrons
cortical 80-85% of nephrons Nephrons that have a short loop of Henle and glomeruli in the superficial region of the cortex Cortex Medulla
juxtamedullary Cortex Medulla15-20% of nephrons Cortex Medulla Nephrons that have glomeruli in the cortex close to the medulla and a long loop of Henle that spans the medulla
