There are water-tight junctions between cells in the stomach, so that no HCl can leak out of the stomach into the abdomen, which are tight junctions.
Option E
Explanation:
The tight junctions are the water tight sealing boundaries through which the content of the stomach do not cross the epithelial lining of the stomach and neither do the outer fluid crosses the epithelial lining inside of it.
The tight junction is established via claudins, which are protein molecules by constituents. They are present in the cell and they pair up with the claudin molecule present on the adjoining or opposite claudin of the other cell, forming branch like tight network.
