Question

The value of GFR in a healthy individual is?

Answer 1

Hint: Nephron is a functional and structural unit of kidney, which comprises a renal tubule and a renal corpuscle. The glomerulus is a tuft of capillaries which is located in the renal corpuscle. The nephron helps in filtering the blood, reabsorption, and rest waste gets excreted in the form of urine.

Complete answer:
The GFR stands for glomerular filtration rate. This is a type of test which is done to check the working of the kidneys. It is used to estimate the amount of blood that could pass from the glomeruli every minute. The tiny filter in the kidney which aids in blood filtration is known as glomeruli.

In a healthy individual the normal range of GFR is 100 to 130 average, $90–120 ml^{-1}min^{-1} 1.73m^2$ in females and $125 mL^{-1}min^{-1} 1.73m^2$ in males. After 40 years of age the GFR tends to decrease as the person ages.

The GFR lower than $15mL^{-1}min^{-1} 1.73 m^2$ could be a sign of failure of the kidney and should be treated immediately.

The test is recommended to the person who has a chronic kidney disease. This chronic kidney disease could also be developed because of urinary blockage, high blood pressure, heart disease, frequent urinary tract infection, family history with a kidney disease, and diabetes.

Note: The functions present in the healthy kidney aids for maintaining an acid- base balance, a fluid balance, regulating the electrolytes, clearing toxins, regulating hormones, regulating blood pressure, and the activation of the vitamin D.
