Solution
Ultrafiltration:
Ultrafiltration is the process in kidneys where large biomolecules such as proteins and sugars are filtered from the blood before the formation of urine.
It occurs under high pressure.
The filtration of blood that occurs through the membranes is so fine that almost all the elements of the plasma, the exception being the proteins move into the lumen of the Bowman’s capsule (a two-walled pouch that covers the glomerulus).
