What is the function of juxta glomerular apparatus (JGA)?
  1. To regulate the glomerular blood flow
  2. To release renin
  3. To stimulate the glomerular filtration rate

JGA has a built-in mechanism for regulation of GFR. It can release renin in response to a fall in GFR, which can stimulate the glomerular blood flow and the GFR back to normal.
