Week 5 Flashcards
urea
major waste product of protein metabolism
homeostasis
stable internal environment with proper balance of water, electrolytes and acids
home/o
unchanging
retroperitoneal
outside or behind the lining of the abdominal cavity. Where kidneys are located.
cortex
outer layer of kidney
medulla
inner layer of kidney
nephron
functional unit of the kidney
glomerulus
part of nephron - cluster of capillaries that filter blood
Bowman’s capsule
part of nephron - cup shaped structure that contains glomerulus.
renal corpuscle
part of nephron - collective term for glomerulus and Bowman’s capsule together
proximal convoluted tubules
part of nephron - hollow tubes located between bowman’s capsule and loops of Henle that are involved in reabsorption
loop of Henle
part of nephron - U shaped turn in convoluted tubule located between the proximal and distal convoluted tubules - involved in reabsorption. Has ascending and descending loop.
distal convoluted tubules
part of nephron - hollow tubes located between loops of Henle and collecting tubules - involved in secretion
collecting tubules
part of nephron - hollow tubes that carry urine from the cortex to the renal pelvis.
glomerul/o
to wind into a ball
hilus
point of attachment or depression - concave part of kidney
calyx/calix
cuplike organ
pyel/o
pelvis
renal pelvis
area of kidney where nephrons collect urine before entering the ureters.
ureters
narrow tubes that carry urine from kidneys to urinary bladder
trigone
triangular portion at the base of the urinary bladder where ureters enter.
micturition
voluntary controlled urination
urethral meatus
external opening of the urethra
turbid
cloudy
erythropoietin
hormone produced by kidney that stimulates rbc production in bone marro
antidiuretic
hormone released by posterior pituitary gland that suppresses urine formation by reabsorbing more water. Abbreviated ADH.
aldosterone
hormone secreted by adrenal cortex that regulates electrolyte balance via reabsorption of sodium
cystography
radiographic study of the urinary bladder after contrast material has been placed via catheter.
retrograde
going backward
intravenous pyelogram
radiographic study of kidney and ureters in which a dye is injected into a vein to define structures more clearly. Abbreviated IVP
pneumocystography
radiographic study of the urinary bladder after air has been placed in the bladder via urethral catheter
retrograde pyelogram
radiographic study of the kidney and ureters in which contrast material is placed directly in the urinary bladder
albuminuria
presence of the major blood protein in urine
anuria
complete suppression of urine production
bateriuria
presence of bacteria in urine
crystalluria
urine with naturally produced angular solid of definitive form (crystals)
