In human physiology, what is the primary function of the Loop of Henle in the mammalian nephron?
Answer and explanation
Correct answer: B. Establishes an osmotic gradient in the renal medulla through countercurrent multiplication to concentrate urine
- Step 1: The loop of Henle operates a countercurrent multiplier mechanism that builds a hypertonic medullary gradient essential for water recovery. Answer: Establishes an osmotic gradient in the renal medulla through countercurrent multiplication to concentrate urine. Why not the others: Filtration occurs in the glomerulus/Bowman's capsule.
