* Podocytes: These are highly specialized cells with foot-like processes that wrap around the capillaries of the glomerulus. They form a filtration barrier called the filtration slit, which prevents large molecules from entering the urine.
* Endothelial cells: These line the capillaries of the glomerulus and have pores called fenestrae that allow for the passage of water, small solutes, and proteins.
It's important to remember that while the glomerulus itself is made of epithelial tissue, it's part of a larger structure called the glomerular filtration unit, which also includes:
* Mesangial cells: These cells are located between the capillaries and help to regulate blood flow through the glomerulus.
* Basement membrane: This is a thin layer of extracellular matrix that surrounds the capillaries and acts as a filter.
So, the glomerulus itself is primarily epithelial tissue, but its function is closely intertwined with the other tissues in the glomerular filtration unit.
