Pathway Through Nephrons with Diuretics

Name each of the letters in the picture

• except I and E

• A: Glomerulus/ bowmans capsule

• B: Proximal convoluted tubule

• C: distal convoluted tubule

• D: collecting duct

• F: ascending loop

• G: loop of Henle

• H: descending loop

Label all the letters

A: glomerulus

B: proximal convoluted tubule

C:descending loop

D: Loop of Henle

E: ascending loop

F: distal convoluted tubule

G: collecting ducts

what diuretic drugs work at the Glomerulus/ Bowmans capsule

no diuretics act here

what drugs act at the proximal convoluted tubule

• Osmotic: Mannitol

• Carbonic Anhydrase Inhibitor: Acetazolamide (diamox)

what drugs act in the distal convoluted tubules

• Thiazide: Hydrochlorothiazide

• Potassium-Sparing: Sprionolactone

what diuretics act in the collecting duct

none act here

What diuretics act on the ascending loop of Henle

• Loop (most potent): Furosemide

  • acts after the osmotic: Mannitol acts in the descending loop of Henle

what diuretic acts on the descending loop of Henle

• Osmotic: Mannitol

  • acts before the Loop: furosemide in the ascending loop
