a) Renal corpuscle

b) Proximal convoluted tubule (PCT)

c) Collecting duct

d) Distal convoluted tubule (DCT)

e) Nephron loop

Answer 1

a) Renal corpuscle

b) Proximal convoluted tubule (PCT)

d) Distal convoluted tubule (DCT)

Question 2

This long duct runs in opposite direction and helps with urine concentration.

Answer 2

nephron loop

Question 3

This duct’s main role is to return previously filtered material back to blood

Answer 3

PCT

Question 4

This structure collects the filtrate coming out of the glomerulus.

Answer 4

glomerular capsule (bowman’s capsule)

Question 5

Its role is to filter blood and collect filtrate.

Answer 5

renal corpuscle

Question 6

This bundle of porous capillaries performs filtration.

Answer 6

glomerulus

Question 7

This is the last structure filtrate flows through before it becomes urine.

Answer 7

DCT

Question 8

Each nephron connects to one, but this structure is shared by many nephrons.

Answer 8

collecting duct

Question 9

This extended network of capillaries branches from the efferent arteriole and wraps around kidney tubules.

Answer 9

peritubular capilllaries

Question 10

The largest vein of a kidney allowing filtered blood to return to system circulation.

Answer 10

renal vein

Question 11

They make the glomeruli and filter blood.

Answer 11

glomerular capillaries

Question 12

They are branching from the renal artery and branch again to form glomeruli.

Answer 12

afferent arterioles

Question 13

This is the vessel that exit from the glomerular capsule

Answer 13

efferent arterioles

Question 14

This is the largest artery of the kidneys, it brings to-be-filtered blood inside.

Answer 14

renal artery
