Chapter 13 - The Urinary System Flashcards
ADH
Antidiuretic hormone
ARF
acute respiratory failure
CRF
chronic renal failure
ESRD
end-stage renal disease
GFR
glomerular filtration rate
GU
genitourinary
IVP
intravenous pyelography
Na
Sodium
SG
specific gravity
UA
urinalysis
UTI
urinary tract infection
Hormone released from pituitary gland that causes water reabsorption in kidneys. Concentrate urine.
Antidiuretic hormone (ADH)
Substance increases blood pressure. Activated in blood by renin, which is enzyme produced in kidneys
Angiotensin
Cuplike cavity in pelvis of kidney. Calix
Calyx
Hormone produced by kidney,stimulates red blood cell production in bone marrow
Erythropoietin (EPO)
Cup shaped structure at beginning of nephron, surrounds glomerus, receives material filtered out of blood. Bowman’s capsule
Glomerular capsule
Fluid and dissolved material that filters out of blood and enter nephron through glomerular capsule
Glomerular filtrate
Cluster of capillaries within glomerular capsule
Glomerulus
Organ of excretion . Filters blood, forms urine which contains metabolic waste and other products to regulate water, electrolyte balance, pH body fluids
Kidney
Voiding of urine. Urination.
Micturition
Microscopic functional unit of the kidney. Work with blood vessels, filters blood and balances composition of urine
Nephron
Outer portion of kidney
Renal cortex
Inner portion of kidney. Includes parts of nephrons and ducts that transport urine.
Renal medulla
Expanded upper end of ureter that receives urine from kidney
Renal pelvis
Triangular structure in the medulla of kidney, made of loops and collecting ducts of nephrons.
Renal pyramid
Enzyme produced by kidney that activates angiotensin in blood
Renin
Triangle at base of bladder formed by openings of two ureters and urethra
Trigone
Return of substances from glomerular filtrate to blood through peritubular capillaries
Tubular reabsorption
Main nitrogenous waste in urine
Urea
Tube carries urine from kidney to bladder
Ureter
Tube carries urine from bladder to outside of body
Urethra
Organ that stores and eliminates urine excreted by kidneys
Urinary bladder
