Which of the following is the primary function of the juxtaglomerular complex?
reabsorption of Na+ and other ions |
concentrating urine |
a system that protects the nephron from some chemicals found in blood |
releases chemical signals that regulate the rate of filtrate formation |
Option 3 (Releases chemical signals that regulate the rate of filtrate formation) is correct
Justification: Juxtaglomerular complex is a structure in kidney which regulates the function of each nephron. This structure is formed by the distal convoluted tubule and glomerular afferent arteriole. It's main function is to regulate blood pressure and filtration rate of glomerulus. So, for this function, macula densa and granular cells of the juxtaglomerular complex release chemicals for the to regulate the rate of formation of the filtrate.
Justification for incorrect options:
Hence, option 3 is the correct answer.
