Final answer:
Tight junctions prevent stomach acid from leaking into the abdomen, forming a watertight seal between epithelial cells that protects internal organs.
Step-by-step explanation:
The type of cellular junction that prevents stomach acid from leaking into the abdomen and digesting internal organs is known as a tight junction. These junctions form a watertight seal between adjacent epithelial cells, preventing the highly corrosive gastric juice from damaging the tissues beyond the stomach lining. The stomach's mucosal barrier is essential because it protects the stomach from self-digestion by using a thick coating of bicarbonate-rich mucus, tight junctions that block penetration of gastric juice, and a rapid turnover of epithelial mucosal cells.
The type of cellular junction that prevents stomach acid from leaking into the abdomen and digesting internal organs is called tight junctions. These tight junctions are found in the epithelial cells of the stomach's mucosa, which meet and form a watertight seal between cells, preventing materials from leaking between them. Tight junctions are typically found in tissues that line internal organs and cavities, providing a barrier against the penetration of gastric juice.
