Flashcards in Chapter 13: Urinary System: From Glomeruli to Your Urethral Opening Deck (29):
1

Removal of small substances from the body such as via the kidneys.

Excretion

2

Kidneys, large intestine, liver, lungs, lymph nodes, skin, and spleen.

Excretory organs

3

Kidneys, ureters, bladder, and urethra.

Urinary system

4

Breakdown products of especially amino acids but also nucleic acids that must be removed from the body.

Nitrogenous waste

5

Nitrogenous waste that, if allowed to accumulate, results in a rising of the pH of tissues.

Ammonia

6

Less-toxic nitrogenous waste product of the chemical reaction between two molecules of ammonia and one of carbon dioxide.

Urea

7

Primary excretory organs involved especially in the production of urine.

Kidneys

8

The blood filtration, tubular secretion, and tubular reabsorption functional units of the kidney.

Nephron

9

Removal of relatively small substances from the plasma.

Blood filtration

10

Network of capillaries from which the initial step of kidney function, blood filtration, occurs.

Glomeruli

11

Material received by Bowman's capsule representing the product of the first step of kidney-mediated filtration of blood.

Glomerular filtrate

12

Nephron receiving point of glomerular filtrate.

Bowman's capsule

13

Carrier of glomerular filtrate through much of the nephron especially within the renal cortex.

Convoluted tubules

14

Immediately post-nephron tubes found within kidneys through which still-forming urine passes.

Collecting ducts

15

Product of kidney function that passes into the renal pelvis and then into ureters.

Urine

16

Product of kidney functioning possessing relatively low levels of water.

Concentrated urine

17

Product of kidney functioning possessing relatively high levels of water.

Dilute urine

18

Tubes connecting kidneys to bladder.

Ureters

19

Collecting organ of the water and wastes excreted by the kidney.

Urinary bladder

20

Tube connecting the bladder to outside of the body.

Urethra

21

Effector of involuntary control over voiding of the bladder.

Internal urethral sphincter

22

Effector of voluntary control over voiding of the bladder.

External urethral sphincter

23

Drug that increases the amount of water present in urine.

Diuretic

24

Clinical term for urination, i.e., the voiding on one's bladder.

Micturition

25

Voluntary control over urination.

Continence

26

Cystitis

Inflammation of the urinary bladder such as caused by urinary tract infections.

27

Kidney stone

Common name for renal calculus.

28

Renal failure

Lack of sufficient filtration of the blood by the kidneys.

29

Hemodialysis

Means of artificial filtration of blood outside of the body as required given reduced kidney functioning.
