What are five characteristics of epithelial tissues?
- Cover organs and the body.
- Line body cavities.
- Line hollow organs.
- Have a free surface.
- Have a basement membrane.
- Avascular
- Cells readily divide.
- Cells tightly packed.
- Cells often have desmosomes.
- Function in protection, secretion, absorption, and excretion.
- Classified according to cell shape and number of cell layers.
What are four functions of epithelial tissues?
- Secretion
- Excretion
- Absorption
