Study Notes
Epithelial Tissue Functions
- Protects the body from external damage and infection
- Regulates the exchange of substances between the body and the environment
- Produces hormones and other secretions
Epithelial Cell Structure
- The apical surface of epithelial cells faces the external environment or a body cavity
- The apical surface is specialized for absorption, secretion, or sensation
- Epithelial cells are bound together by tight junctions, desmosomes, and adherens junctions
Basement Membrane
- A thin layer of fibrous tissue that separates epithelial tissue from underlying connective tissue
- Provides structural support and regulates the movement of molecules between the two tissues
Characteristics of Epithelial Tissue
- Avascular, meaning they do not have a direct blood supply
- Receive oxygen and nutrients by diffusion from nearby blood vessels
- Form continuous sheets that cover the body surface and line body cavities
