Question

Quizplus · Accepted Answer

Macula densa cells are chemoreceptors located in the wall of the distal convoluted tubule of the kidney. They respond to changes in the solute content of the filtrate, particularly changes in sodium chloride levels. This information is then relayed to the juxtaglomerular cells, which regulate the production and release of renin, an important hormone in the control of blood pressure and fluid balance. Mesangial cells are important for the structural integrity of the glomerulus, while podocytes are specialized cells that form part of the filtration barrier in the kidney.
