What is the main function of Juxta Glomerular Apparatus (JGA)?

Options

  1. AFiltration of blood
  2. BRegulation of GFR
  3. CRelease of Rennin
  4. DStimulation of Tabular Blood Flow

Correct answer

B. Regulation of GFR

Step-by-step solution

The amount of the filtrate formed by the kidneys per minute is called glomerular filtration rate (GFR). GFR in a healthy individual is approximately 125 ml/minute, i.e., 180 litres per day ! The kidneys have built-in mechanisms for the regulation of glomerular filtration rate. One such efficient mechanism is carried out by juxta glomerular apparatus (JGA). JGA is a special sensitive region formed by cellular modifications in the distal convoluted tubule and the afferent arteriole at the location of their contact. A
