The concentration gradient in the medulla is created by
-
loop of henle
-
glomerulus
-
bowman's capsule
-
nephron
A
Correct answer
Explanation
In the kidney, the loop of Henle (or Henle's loop or ansa nephroni) is the portion of the nephron that leads from the proximal convoluted tubule to the distal convoluted tubule. The loop has a hairpin bend in the renal medulla. The main function of this structure is to create a concentration gradient in the medulla of the kidney.
