What is glomerular filtration rate (GFR)?

Options

  1. AThe amount of blood filtered by the kidneys per minute
  2. BThe amount of plasma filtered by the kidneys per minute
  3. CThe amount of filtrate formed by the kidneys per minute
  4. DThe amount of urine formed by the kidneys per minute

Correct answer

C. The amount of filtrate formed by the kidneys per 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
