The Urinary Tract Flashcards
Antiduretic hormone
Hormone produced in the pituitary gland to control the reabsorption of water the renal tubules
Aldosterone
Hormone produced by the adrenals to contain sodium reabsorption and potassium excretion
Bowman’s capsule
Cup-like capsule enclosing each glomerulus
Erythropoietin (EPO)
Hormone produced by the kidney to stimulate the production of red blood cells in the bone marrow
Filtration
Passage of substances from the glomerulus to BowMan’s capsule
Glomerulus
Collection of capillaries in the renal cortex where filtration takes place
Kidney
Pair of retroperitoneal bean-shaped organs where urine is formed
Nephron
The functional unit of the kidney
Nitrogen
Electrolyte component of protein and amino acids
Nitrogenous wastes
Waste product of protein metabolism; excreted in urine
Potassium
Electrolyte secreted from the bloodstream to the renal tubules and then excreted in the urine
Reabsorption
Substances return to the bloodstream from the renal tubules
Renal cortex
Outer section of the kidney
Renal medulla
Inner section of the kidney
Renal pelvis
Central collecting region of the kidney
Renin
Proteolytic enzyme produced by the kidney to regulate blood pressure
Sodium
Electrolyte in the blood and urine; regulated by the kidney
Urea (BUN)
Non-protein nitrogenous waste that results from protein, it is converted to ammonia. Ammonia is then sent to the liver to be converted to urea which is then excreted in the urine
Ureter
Tube that carries urine from the kidneys to the urinary bladder
Urethra
Tube that carries urine from the urinary bladder to the outside of the body
Uric acid
Metabolic by-product produced by the liver; excreted in the urine
Urinary bladder
Sac that temporarily urine
Urinary catheterisation
Catheter placed in the urethra to the urinary bladder to obtain a urine sample or relieve a urinary obstruction
Urine
Water and waste products produced by the kidneys and stored in that urinary bladder
Voiding
Emptying of urine from the urinary bladder. Also called micturition or urination
Azotemia
Increase in non-protein nitrogenous wastes in the blood. Also called uremia
Calculus
Another name for a stone. Calculus is most often used to describe the small sedimentary particular in urine
Dialysis
Separation of waste products from the bloodstream
Diuresis
Increased excretion of urine
Enuresis
Inability to control excretion; also called incontinence
Feline idiopathic cystitis (FIC)
Inflammation of the bladder due to an unknown cause
Feline lower urinary tract disease (FLUTD)
Disease with a collection of symptoms including cystitis, urethritis, hematutia, dysuria, and crystalluria. Also know as feline urological syndrome (FUS)
Free catch
Also known as a voided sample, this is the collection of urine into an open container
Perineal urethroetomy
New opening in the area between the annum and scrotum to correct FUS
Pollakiuria
Frequent urination
Polycystic kidney
Fluid-filled sac within or upon the kidney; the most common congenital renal defect
Renal Colic
Pain caused by stones in the kidney
Renal Ischemia
Lack of blood flow to the kidney
Stranguria
Straining to urinate; slow or painful urination
Urinalysis
Separation of urine into its components
Urethral stricture
Tightening or narrow of the urethra
Urinary retention
Inability to completely empty the bladder
Urine specific gravity
Measurement of the density of urine. This measures the weight of dissolved substances in the urine and the dehydration status of the patient based on urine concentration
