part G is the
ureter
urethra
renal artery
renal vein
Part B is the
cortex
medulla
glomerulus
renal pyramid
Which label shows the urethra?
A
B
C
D
Which part of the nephron is the glomerulus?
1
2
6
8
Name the part of the nephron where glucose is reabsorbed
2
3
6
7
What takes place in the Bowman's capsule?
ultrafiltration
excretion
reabsorption of water by osmosis
reabsorption of glucose
Which part(s) of the nephron are affected by anti-diuretic hormone ADH?
proximal convoluted tubule
loop of Henle
Bowman's capsule
distal convoluted tubule
collecting duct
sodium and postassium ions are pumped out of the ascending limb of the loop of the Henle to
create a high water potential in the medulla
create a low water potential in the medulla
excrete excess ions into the urine
allow water to be reabsorbed into the proximal convoluted tubule by osmosis
Which structure carries blood that is very low in urea?
G
F
D
E
Which of the following is nitrogenous waste?
urea
salts
amino acids
glucose
What would you find in the urine of a healthy person? Choose all that apply.
salts
water
urea
glucose
proteins
What is filtered out of the blood at 1? Choose all that apply.
salts
water
glucose
proteins
urea
What returns to the capillaries at 2? Choose all that apply.
salts
water
glucose
proteins
urea
ADH causes specific protein channels to move into the membranes of certain cells in the nephron so that more water can be absorbed by osmosis. What are these called?
aquaporins
active transport
tight junctions
desmosomes
The substances remaining in the collecting duct after passing through the nephron make up
urea
urine
filtrate
filtered blood
ADH
Inhibits the absorption of water in the proximal convoluted tubule
Inhibits the absorption of water in the distal convoluted tubule
Increases the absorption of water in the proximal convoluted tubule
Increases the absorption of water in the distal convoluted tubule
