Filtration slits
Filtration slits (pronunciation: /fɪlˈtreɪʃən slɪts/) are specialized structures in the kidney that play a crucial role in the process of urine formation. They are part of the glomerulus, a network of tiny blood vessels in the kidney where the filtration of blood takes place.
Etymology
The term "filtration slits" is derived from the English words "filtration", which refers to the process of filtering, and "slits", which means narrow openings.
Function
Filtration slits are narrow gaps between the podocytes, specialized cells that wrap around the capillaries of the glomerulus. These slits act as a filter, allowing small molecules such as water, glucose, and ions to pass into the Bowman's capsule, while preventing larger molecules like proteins and blood cells from passing through.
