Question 2

What are some characteristics of epithelium tissue (6)

Answer 2

1. Mostly composed of cells: Epithelial tissue consists of cells with very little extracellular matrix between them.
2. Covers body surfaces: Epithelial tissue covers body surface and forms glands derived developmentally from the body surface.
3. Distinct cell surface: Most epithelial cells have at least one free surface. Where cells are exposed and do not attach to other cells.
4. Cell and matrix connection: Specialized cell contact bind adjacent epithelial cells together and the extracellular matrix to the basement membrane.

5 Nonvascular: Blood vessels do not penetrate the basement membrane to reach the epithelial. All nutrients and gasses from the blood are transported through diffusion to the epithelium

6. Capable of regeneration- Epithelial tissue has the ability to replaced damaged cells with new epithelial cells.
