Test your knowledge on nephron function and osmolarity!

by Dr. Sarah Hayat

What is the initial osmolarity of fluid entering the loop of Henle from the proximal tubule?

200 mOsm/L

300 mOsm/L

100 mOsm/L

What is the maximum concentration gradient the thick ascending limb can establish?

100 mOsm/L

400 mOsm/L

200 mOsm/L

Which part of the nephron actively reabsorbs NaCl but is impermeable to water?

Descending limb of loop of Henle

Proximal tubule

Thick ascending limb

What drives water out of the descending limb of Henle's loop?

High hydrostatic pressure

ADH secretion

Osmotic gradient created by NaCl in the interstitium

What is the final osmolarity of the renal medullary interstitium under maximum concentrating conditions?

1200–1400 mOsm/L

800 mOsm/L

1000 mOsm/L

Which hormone increases water permeability in the cortical collecting duct?

Renin

Aldosterone

ADH

In the absence of ADH, the cortical collecting duct is:

Actively reabsorbing water

Highly permeable to urea

Impermeable to water

Which contributes most to the hyperosmolarity of the inner medulla during antidiuresis?

NaCl from distal tubule

Urea reabsorption

Water secretion

Which urea transporter is found in the thin descending limb of the loop of Henle?

UT-B1

UT-A1

UT-A2

Which structures act as countercurrent exchangers in the kidney?

Distal convoluted tubule

Loop of Henle

Vasa recta

You can integrate the game into an LMS compatible with LTI 1.1 or LTI 1.3 such as Canvas, Moodle, or Blackboard. This way, the scores will be automatically saved into the platform’s gradebook.
