Chapter 6 Flashcards
Kidneys
Two bean shaped organs located on each side of the vertrebal column. Function: to remove waste products from the blood and to aid in maintaining water and electrolyte balances.
nephron
urine-producing microscopic structure. Aprx 1 million nephrons in each kidney.
glomerulus (pl. glomeruli)
cluster of capillaries at the entrance of the nephron. The process for filtering the blood, thereby forming urine, begins here.
renal pelvis
funnel shaped reservoir that collects the urine and passes it to the ureter.
hilum
indention on the medial side of the kidney where the ureter leaves the kidney.
ureters
two slender tubes, approx 10-13 inches long, that receive the urine from the kidneys and carry it to the posterior portion of the bladder.
urinary bladder
muscular, hollow organ that temp. holds the urine.
urethra
lowest part of the urinary tract, through which the urine passes from the urinary bladder to the outside of the body. (1.5 inches for W, 8 inches for M)
urinary meatus
opening through which the urine passes to the outside.

azotemia
condition of urea in the blood (a toxic condition resulting from disease of the kidney in which waste products are in the blood that are normally excreted by the kidney)
cystitis
inflammation of the bladder
cystocele
protrusion of the bladder
cystolith
stone in the bladder
glomerulonephritis
inflammation of the glomeruli of the kidney
hydronephrosis
abnormal condition of water in the kidney (because of an obstruction)
nephritis
inflammation of a kidney
nephroblastoma
kidney tumor containing developing cells (malignant)
nephrohypertrophy
excessive development (increase in size) of the kidney
nephrolithiasis
condition of stone(s) in the kidney
nephroma
tumor of the kidney
nephromegaly
enlargement of a kidney
nephroptosis
drooping kidney
pyelitis
inflammation of the renal pelvis
pyelonephritis
inflammation of the renal pelvis and the kidney
ureteritis
inflammation of a ureter
ureterocele
protrusion of a ureter (distally into the bladder)
ureterolithiasis
condition of stones in the ureters
ureterostenosis
narrowing of the ureter
urethrocystitis
inflammation of the urethra and the bladder
epispadias
congenital defect in which the urinary meatus is located on the upper surface of the penis.
hypospadias
congenital defect in which the urinary meatus is located on the underside of the penis; a similar defect can occur in the female.
polycysitic kidney disease
condition in which the kidney contains many cysts and is enlarged
