Match the types of epithelial tissue to their characteristics:

Body Tissues

Tissue is a group of cells with similar structure and function.
Four primary tissue types: epithelial, connective, nervous, and muscle.
Epithelial tissue (epithelium) forms boundaries, protects, secretes, absorbs, and filters.
- Found lining body cavities, hollow organs, and as the outer layer of skin.
Connective tissue supports, protects, and binds other tissues together.
- Examples include bones, tendons, and fat.
Nervous tissue is responsible for internal communication.
- Found in the brain, spinal cord, and nerves.
Muscle tissue contracts to cause movement.
- Skeletal muscle: attaches to bones.
- Cardiac muscle: found in the heart.
- Smooth muscle: lines the walls of hollow organs.

Epithelial Tissue Characteristics

Cells fit closely together and form sheets.
Rich in tight junctions and desmosomes, except for glandular tissue.
Apical surface is the free surface of the tissue.
Basal surface rests on a basement membrane (non-cellular layer).
Avascular (no blood supply).
Regenerate easily if well-nourished.

Classification of Epithelia

Number of cell layers:
- Simple: one layer.
- Stratified: more than one layer.
Cell shape:
- Squamous: flat and thin.
- Cuboidal: cube-shaped.
- Columnar: tall and column-shaped.
