Explanation:
That is all up to ones opinion no one really knows because no one that is living now was alive then all we can go by is secondary sources to let us know
The macula densa cells monitor the NaCl content of the filtrate entering the distal convoluted tubule.
Define juxtaglomerular apparatus.
The juxtaglomerular apparatus, often referred to as the juxtaglomerular complex, is a kidney structure that controls how each nephron, or functional unit of the kidney, performs.
What are macula densa cells ?
According to the traditional paradigm, the distal nephron's macula densa cells serve as salt sensors and send chemical signals to the juxtaglomerular apparatus to regulate key kidney activities like renal blood flow, glomerular filtration, and renin release.
