Which cells of the distal tubule detect sodium concentration in the filtrate?
Show answer and explanation
Correct answer: Macula densa cells
Macula densa cells are specialized epithelial cells in the distal tubule. They monitor sodium concentration and help regulate filtration through the juxtaglomerular apparatus.
