Flashcards in Chapter Seven- Urinary Deck (75):
1

Calyx or Calix

Cup-like collecting region of the renal pelvis

2

Catheter

Tube for injecting or removing fluids

3

Cortex

Outer region of an organ; the renal cortex is the outer region of the kidney

4

Creatinine

Nitrogenous waste excreted in urine

5

Electrolyte

Chemical element that carries an electrical charge when dissolved in water; necessary with function of muscles and nerves; kidneys

6

Erythropoietin (EPO)

Hormone secreted by the kidney to stimulate the production of red blood cells by bone marrow

7

Filtration

Process whereby some substances, but not all, pass through a filter

8

Glomerular capsule

Enclosing structure surrounding each glomerulus. (Bowman capsule; collects the material that is filtered from the blood through the walls of the glomerulus)

9

Glomerulus

Tiny ball of capillaries in the kidney

10

Hilum

Depression in an organ where blood vessels and nerves enter and leave

11

Kidney

One of two bean shaped organs on either side of the backbone in the lumbar region; filters nitrogenous wastes from the bloodstream to form urine

12

Meatus

Opening or canal

13

Medulla

Inner region of an organ

14

Nephron

Combination of glomerulus and renal tubule where filtration, reabsorption, and secretion take place in the kidney; functional unit of kidney; 1 million per kidney

15

Nitrogenous waste

Substance containing nitrogen an excreted in urine

16

Potassium

Electrolyte regulated by the kidney so that a proper concentration is maintained within the blood; muscle contraction and nerve impulses

17

Reabsorption

Process where renal tubules return materials necessary to the body back in the bloodstream

18

Renal artery

Blood vessel that carries blood to the kidney

19

Renal pelvis

Central collection region in the kidney

20

Renal tubule

Microscopic tubes in the kidney where urine is formed after filtration

21

Renal vein

Blood vessel that carries blood away from the kidney and toward the heart

22

Renin

Hormone secreted by the kidney; raises blood pressure by influencing vasoconstriction

23

Sodium

An electrolyte regulated in the blood and urine by the kidneys; needed for proper transmission of nerve impulses, heart activity, and other metabolic functions

24

Trigone

Triangular area in the urinary bladder

25

Urea

Major nitrogenous waste excreted in urine

26

Ureter

One of two tubes leading from the kidneys to the urinary bladder

27

Urethra

Tube leading from the urinary bladder to the outside of the body

28

Uric acid

Nitrogenous waste excreted in urine

29

Urinary bladder

Hollow, muscular sac that holds and stores urine

30

Urination (voiding)

Process of expelling urine; micturition
