7

8

Glomerulus

Cluster of capillaries that filter blood

9

Bowman's capsule

Cup-shaped structure that contains the glomerulus

10

Proximal convoluted tubules

Hollow tubes located between Bowman's capsule and loops of Henle that are involved in reabsorption

11

Loop of Henle

U-shaped turn in the convoluted tubule of the kidney located between the proximal and distal convoluted tubules that is involved in reabsorption; has ascending and descending loop

12

Distal convoluted tubules

Hollow tubes located between the loops of Henle and the collecting tubules that are involved in secretion

13

Collecting tubules

Hollow tubes that carry urine from the cortex to the renal pelvis

14

Urination

Elimination of urine from the body

15

Excretion; Voiding; Elimination

Elimination of a substance
Can be used in other body systems (not just pertaining to the urinary system)

16

Micturition

Elimination of urine from the body (it implies voluntary control of the sphincter muscles of the urinary tract; this voluntary control of voiding urine is learned and implies a more intelligent form of animal life)

17

Erythropoietin

Hormone produced by the kidney that stimulates RBC production in the bone marrow

18

Antidiuretic

Hormone released by the posterior pituitary gland that suppresses urine formation by reabsorbing more water
(abbrev. ADH)

19

ADH

= Antidiuretic
Hormone released by the posterior pituitary gland that suppresses urine formation by reabsorbing more water

20

Aldosterone

Hormone secreted by the adrenal cortex that regulates electrolyte balance via the reabsorption of sodium

21

Cystocentesis

Surgical puncture of the urinary bladder, usually to collect urine (usually performed with a needle an syringe)

22

Cystogram

Radiographic film of the urinary bladder after contrast material has been placed in the urinary bladder via a urethral catheter

23

Retrograde

Going backward
Can be used to describe the path that contrast material takes (if the contrast material goes in reverse order of how urine normally flows in the body, it is referred to as retrograde)

24

Intravenous pyelogram

abbrev. IVP
Radiographic study of the kidney (especially the renal pelvis) and ureters in which a dye is injected into a vein to define structures more clearly. The urinary bladder also may by visualized better with an intravenous pyelogram.

25

Pneumocystography

Radiographic study of the urinary bladder after air has been placed in the bladder via a urethral catheter

26

Retrograde pyelogram

Radiographic study of the kidney and ureters in which a contrast material is placed directly in the urinary bladder

27

Urinalysis

Examination of urine components
abbrev. UA

28

Urinary catheterization

Insertion of a tube through the urethra into the urinary bladder (usually to collect urine)

29

Azotemia

Presence of urea or other nitrogenous elements in the blood

30

Calculus

Abnormal mineral deposit

31

Casts

Fibrous or protein materials found in the urine with renal disease or another abnormality

32

Crystals

Naturally produced angular solid of definitive form

33

Cystitis

Inflammation of the urinary bladder

34

Epispadias

Abnormal condition in which the urethra opens on the dorsum of the penis

35

FLUTD

= Feline Lower Urinary Tract Disease
Common disease in cats in which cystitis, urethritis, and crystalluria are found
In male cats, urethral obstruction is commonly associated with this disease

36

Glomerulonephritis

Inflammation of the kidney involving the glomeruli

37

Hydronephrosis

Dilation of the renal pelvis as a result of an obstruction to urine flow

38

Hydroureter

Distention of the ureter with urine caused by any blockage

39

Hypospadias

Abnormal condition in which the urethra opens on the ventral surface of the penis

40

Inappropriate urination

Eliminating urine at the wrong time or in the wrong place

41

Incontinence

Inability to control excretory functions

42

Interstitial cystitis

Inflammation within the wall of the urinary bladder

43

-lithiasis

Suffix meaning the presence of stones or calculi, as in nephrolithiasis (disorder characterized by the presence of kidney stones), urolithiasis (disorder characterized by the presence of urinary bladder stones), and ureterolithiasis (disorder characterized by the presence of stones in the ureters)

44

Nephritis
