The glomerular filtrate contains

Ultrafiltration is the first step in urine formation. This is the filtration of blood and is carried out by glomerulus and thus is also known as glomerular filtration. This takes place through three layers that forms the filtration membrane. The podocytes present in the inner layer of Bowmans capsule play an important role in this filtration. When blood is filtered through this membrane. Thus almost all the substances are filtered except proteins and blood cells. Thus urea, uric acid, glucose, water is filtered and thus enters the Bowman's space.
