Answer:
2) They are vascularized is incorrect statement because epithelia tissues are avascular because they lack blood vessels.
Explanation:
- All of the organs within and outside of the human body have epithelial tissues covering their surfaces. As a result, epidermal cells have an apical surface, which is the only edge that is unconnected to other cells.
- An inner membrane, which is partially made by epithelial cells, is what holds epithelial tissue's opposite end (the basal surface) in place. Connective tissues are located below the basement membrane.
- Epithelial tissues are avascular because they lack blood vessels.
- Because connective tissues frequently have a high blood flow, the surrounding connective tissue supplies the epithelial tissue with vital nutrients from the blood.
