Intercellular passage of ions from the luminal surface of
|\ |\ |\ |\ |\ |\ |\ |\ |\



the intestines to the lamina propria is prevented by the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\



presence of ? |\ |\




Desmosomes
Belt desmosomes
|\




Hemidesmosomes
Gap junctions
|\

,Tight junctions/zonula occludens
|\ |\




Tight junctions/ Zonula occludens
|\ |\ |\




Water is prevented from passing through the epithelial
|\ |\ |\ |\ |\ |\ |\ |\



cells because of the zonula occludens. They are sealants
|\ |\ |\ |\ |\ |\ |\ |\ |\



in between the surface of cells except in the sertoli cells.
