Ch 26 Lec 1 - Urinary System Flashcards
urinary organ produces urine
kidney
urinary organ that takes urine to bladder
ureter
kidney is covered by these three things
renal capsule, renal fascia, perinephric adipose
superficial structure of kidney that is penetrated by renal artery, vein, and ureter penetrate
hilus
two layers of kidney
renal medulla, renal cortex
outer granular layer of kidney
renal cortex
renal papilla of renal pyramids empties into blank
minor calyces
minor calyx empties into blank
major calyces
major calyces empties into blank
renal pelvis
renal pelvis turns into blank
ureter
after going into glomerulus, blood in kidneys go to blank, then blank, then blank
efferent arterioles, peritubular capillaries, venules
functional unit of the kidney and there are blank per kidney
nephron, 1 million
nephrons are not blank if damages
replaced
amount of functional nephron essential for survival
1/3
two regions of nephron
renal corpuscle, renal tubule
renal corpuscle is made of blank and blank
glomerulus and bowman’s capsule
cluster of capillaries off afferent arteriole
glomerulus
glomerulus has blank endothelium on capillaries
fenestrated
two layers of renal corpuscle
visceral, parietal
part of visceral layer that adheres to the glomerulus
podocytes
podocytes are highly blank cells
branched
branches of podocytes are called blank
pedicels
outer wall of renal glomerular capsule
parietal layer
the filtration of blood is aka blank
glomerular filtration
plasma becomes blank in the capsule
filtrate
continues from renal corpuscle
proximal convoluted tubule
proximal convoluted tubule is made of blank epithelium with a brush border
cuboidal
proximal convoluted tubule absorbs blank percent of filtrate
80
proximal convoluted tubule only filters out blank nutrients and blank percent of essential ions
organic, 60
this has a descending and ascending limb
loop of henle
limb of loop of henle that is thin
descending
limb of loop of henle that is thick
ascending
renal tubule that is close to renal corpuscle
distal convoluted tubule
distal convoluted tubule is for blank and blank
reabsorption, secretion
blank is reabsorbed due to blank in distal convoluted tubule
Na+, aldosterone
water is reabsorbed due to blank in distal convoluted tubule
ADH
distal convoluted tubule secretes blank and blank
H+, K+
distal convoluted tubule drains into blank tubules then collecting blank
collecting, ducts
collecting ducts go to blank ducts then blank then blank then blank then blank
papillary, minor calyces, major calyces, renal pelvis, ureter
final water adjustments are made in the blank and blank
distal convoluted tubule, collecting ducts
if permeability of collecting system is low then there are blank amounts of blank urine and less blank presence
large, dilute, adh
if permeability of collecting system is high then there are blank amounts of blank urine and more blank presence
smaller, concentrated, adh
specialized cells that monitor ion concentration of distal convoluted tubule filtrate
macula densa
juxtaglomerular complex is made of these two thigns
distal convoluted tubule, afferent arteriole
these cells are in the afferent arteriole and are smooth muscle cells in arteriole wall
juxtaglomerular cells
in the juxtaglomerular complex, when Na+ and Cl- is low then blank secretes blank
macula densa, renin
these constrict the afferent arteriole to increase filtrate
juxtaglomerular cells
two types of nephrons
cortical, juxtamedullary
short nephron mainly in cortex and produces standard blank
cortical, urine
nephron where corpuscles are in medulla and produces blank urine
juxtamedullary, concentrated
glomerulus filters out blank liters per day of filtrate
180
blank percent of water is reabsorbed and blank percent of filtrate enters renal pelvis
99, 1-5%
four hormones that affect urine concentration
pth, aldosteroone, renin, adh
hormone that increases calcium reabsorption
pth
hormone that increases Na reabsorption and K excretion
aldosterone
hormone that increases filtrate concentration
renin
hormone that increases water reabsorption in distal convoluted tubule and collecting duct
adh
ureters are lined with blank
mucous membranes
urine can blank but not leave through the opening flap of bladder
enter, leave
hollow muscular sac that is behind the pubic symphis
bladder
bladder is made of blank fibers, blank muscles and many blank when empty
elastic, involuntary, rugae
in men the bladder is superior to blank
prostate
in women, bladd is inferior to blank
uterus
area at base of bladder bounded by openings of ureter and urethra
trigone
these glands secrete mucous in urethra
urethral
female urethra is blank than males
shorter
release that is controlled by two sphincters and both sphincters must be open to urinate
micturition
two sphincters of micturition
internal urethral, external urethral
micturition sphincter that is involuntary
internal urethral
micturition sphincter that is voluntary
external urethral
loss of urine without voluntary control
incontinence
micturition is the combination of blank and blank
reflex, urination
