Explanation:
Detailed explanation-1: -Answer and Explanation: Because of its high mitotic rate, epithelial tissue has the ability to heal itself so rapidly. The lower layers of epithelial tissue has a high amount of stem cells and these stem cells divide constantly so that they can replace the cells that are above them.
Detailed explanation-2: -The homeostatic replacement of cells varies substantially among different epithelia. The epithelium of the intestine completely self-renews within ∼5 days. By contrast, interfollicular epidermis takes ∼4 weeks to renew, whereas the lung epithelium can take as long as 6 months to be replaced.
