Chapter 16 - Genitourinary System Flashcards
Bowman’s capsule (renal capsule)
cup-shaped end of renal tubule containing the glomerulus
calyx
cup-shaped part of the renal pelvis through which urine passes from the renal tubules
cortex
the outer layer of the kidney
glormerulus
collection of coiled intertwined capillaries located in the kidney cortex
kidneys
two organs on the posterior abdominal wall that filter the blood, excreting the end products of body metabolism in the form of urine, and regulating body mineral levels
medulla
the inner layer of the kidney
nephron
the structural and functional unit of the kidney, the parenchyma, numbering about a million and capable of forming urine
renal artery
one of two large arteries branching from the abdominal aorta that supplies blood to kidneys, adrenals, and ureters
renal pelvis
the funnel-shaped expansion of the upper end of the ureter
renal tubule
long, twisted tube leading from glomerulus to collecting tubules
renal vein
one of two large veins that carries blood from the kidneys to the inferior vena cava
ureter
the tubular structure through which urine passes from the kidney to the bladder
urethra
the passage through which urine is discharged from the bladder to the body exterior
urinary bladder
musculomembranous sac that stores urine, receiving it through the ureters and discharging it through the urethra
urinary meatus
opening of the urethra to the exterior
azoturia
excess urea (or other nitrogen compounds) in urine
calculus (renal) (pl., calculi)
kidney stone(s)
cystitis
inflammation of the urinary bladder
dialysis
the process of using an artificial kidney to filter waste materials from the body
“floating kidney”
a kidney not securely fixed in the usual location because of a birth defect or injury
glomerulonephritis
nephritis with inflammation of the capillary loops in the renal glomeruli
hydroneophrosis
distention of the renal pelvis with urine, caused by obstruction of the ureter
nephrolithiasis
a condition marked by the presence of renal calculi (stones)
nephroptosis
downward displace of a kidney
