Basal Lamina- This component acts as an attachment to the rest of the structure as well and separates the epithelium from the connective tissue. It also aids in filtration.
Zonula Occludens- These structures are also known as tight junctions. They create a barrier which allows for tight seals, causing selective permeability.
