retroperitoneal

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
