MCQ ON URINE FORMATION class 11 for NEET

INTRODUCTION:-

URINE FORMATION:-
Urine formation involves three main processes namely glomerular filtration, reabservation and secretion, that takes place in different parts of the nephron.
The first step in urine formation is the filtration of blood, which is carried out by the Glomerular and is called glomerulus filtration.

On in average 1100 to 1200 ml of blood is filtered by the kidney per minute which constitution roughly 1/ 5 of the blood pump out by each ventricle of the heart in a minute. The glomerular capillary blood pressure causes filtration of blood through three layers the endothelium of glomerular blood vessels, the epithelial of bowman’s capsule and basement membrane between these two layers.
Bloody is filtered so finally through the basement membrane that allow almost all the constituent of the plasma except the protein pass on to the lumen of the bowman’s capsules. Therefore it is considered as a process of ultra filtration.

The amount of filtrate formed by the kidney per minute is called Glomerular filtration rate.
GFR in healthy individual is approximately 125 ml per minute that is 180 liters per day.

The kidney have built in mechanism for a regulation of glomerular filtration rate.
One such efficient mechanism is carried out by justa glomerular apparatus.
JGA is a special sensitive region formed by cellular modification in the DCT.
