Explanation:
Detailed explanation-1: -Epithelial tissues provide the body’s first line of protection from physical, chemical, and biological damage. The cells of an epithelium act as gatekeepers of the body, controlling permeability by allowing selective transfer of materials across its surface. All substances that enter the body must cross an epithelium.
Detailed explanation-2: -The high regenerative capacity of this epithelium, with stem cells able to self-renew constantly throughout life, makes this tissue ideal for regenerative medicine approaches. At the same time, however, the continuous proliferation of intestinal stem cells accumulates mutations that can promote cancer growth.
