Question 15

Kidneys do this :

Answer 15

Filter blood
Create urine
Stabilize water balance
Maintain blood pressure
Produce active form of vitamin D

Question 16

functional unit of the kidney; microscopic tubules that use various pressure levels to remove wastes and reabsorb important molecules and water

Answer 16

Nephron

Question 17

After passing through the renal artery, blood enters the nephron __________ before flowing into the ___________.

Answer 17

capillaries, glomerulus

Question 18

Small dense group of capillaries in nephron where materials are filtered from the blood

Answer 18

glomerulus

Question 19

left over material from glomerulus after filtration which includes:

water
urea
glucose salts
other small molecules

Answer 19

filtrate

Question 20

Urine contents:

Answer 20

water (95%)
urea
salts
excess organic molecules

Question 21

Why does filtrate move back through the tubules after having been filtered?

Answer 21

So that water and other important substances can be reabsorbed by the capillaries and entered into the blood

Question 22

How do the kidneys control blood pressure?

Answer 22

By constricting or dilating blood vessels

Question 23

hormone produced by the kidneys that regulates blood pressure by retaining or removing water and salt

Answer 23

Renin

Question 24

help control the production of red blood cells

Answer 24

Kidneys

Question 25

Answer 25

Blood pressure
