What is the normal range of glomerular filtration rate (GFR) in a healthy individual?
Options
- A50-60 ml/minute
- B100-110 ml/minute
- C125-135 ml/minute
- D180-190 litres per day
Correct answer
C. 125-135 ml/minute
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
