Summary Introduction
Introduction:
The organs with a lumen have different molecules in it that are undergoing various reactions. So, a molecule entering the lumen or even leaving the lumen will hinder the reaction. Thus, the epithelial cells here have a tight junction to halt any such unwanted movements of molecules.
