Question

What is the function of epithelial tissue in our body?

Answer 1

Answer:

Functions of epithelial tissue:

• i. Epithelial tissue covers the body outside and lines the various cavities inside.
• ii. Epithelial tissue lines the hollow organs, body cavities, blood vessels and ducts.
• iii. Cells are rested on thin, doubled layered, non-cellular basement membrane.
• iv. Epithelial tissue has nerve supply of its own.
• v. Epithelial tissue is avascular (a = without, vascular = vessel), i.e. it lacks its own blood supply and hence, obtains nutrients which diffuse out of blood vessels.
• vi. Epithelial tissue has the power of division and regeneration. The old injured dead cells are sloughed off regularly and are replaced by new ones.
