____Here is your answer Sistah!____
=================================

☛Glomerular Filtration Rate :--
===========================
It is the rate of filtration of blood through the GLOMERULUS during the first step of urine formation per minute.

☑️In a healthy adult GFR is about 125ml/minute.

◼️And this process is known as ultra- filtration.
Because there are very ultra filtration of blood and urea is take place.

☑️The factors affecting Glomerular filtration rate :---
=================================

◼️1.) Renal blood flow :---
======================
It the rate of blood flow through the renal tubules are high then GFR will automatically increase.

◼️2.) Concentration of NaCl :---
==========================
If the concentration of NaCl is high in fluid then GFR will also increase.

◼️3.) Glomerular Capillaries Pressure :---
=================================
It is the pressure exerted on the wall of Glomerular capillarie's wall by blood.
If is high then GFR would also be high.

◼️4.) Colloidal Osmotic Pressure :---
===============================
It is the pressure exerted by the blood protein on the blood capillaries.
If it will high then the GFR will decrease.
Because Proteins can pass through renal tubules and thus releases the pressure.

◼️5.) Arterial Pressure :---
======================
If this pressure will high then the GFR will automatically increase.
Thus, this pressure promotes GFR.

Hope it will help you!
Thanks!!☺️
