What is juxta glomerular apparatus (JGA)?
Options
- AA special sensitive region in the Bowman’s capsule
- BA special sensitive region in the distal convoluted tubule and the afferent arteriole
- CA special sensitive region in the renal tubule
- DA special sensitive region in the vasa recta
Correct answer
B. A special sensitive region in the distal convoluted tubule and the afferent arteriole
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
