GENERAL HISTOLOGY

Detailed explanation-1: -Glomerular filtration is the first step in urine formation and constitutes the basic physiologic function of the kidneys. It describes the process of blood filtration in the kidney, in which fluid, ions, glucose, and waste products are removed from the glomerular capillaries.

Detailed explanation-2: -Filtration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle. About 20% of the plasma volume passing through the glomerulus at any given time is filtered. This means that about 180 liters of fluid are filtered by the kidneys every day.

Detailed explanation-3: -The glomerular capsule (also known as Bowman’s capsule) is the filtration unit of the glomerulus. It has tiny slits where some filtrate may pass through into the nephron. Water, sodium ions, bicarbonate ions, potassium ions, glucose. and ammonia are able to pass the membranes of the glomerular capsule.
