Groups of similar cells that form continuous sheets—coverings and linings of surfaces—providing protection, absorption, filtration, and secretion.

Epithelial cells come in three fundamental shapes: squamous (flattened), cuboidal (cube-shaped), and columnar (column-shaped).

The layer beneath epithelial cells that anchors them to connective tissue.

Epithelial tissue lacks its own blood vessels, and is nourished by connective tissue.

A single layer of epithelial cells.

Epithelial tissue consisting of multiple layers of cells providing greater protection than simple epithelium.

A single layer of flattened epithelial cells. It allows absorption and filtration because of its thin structure.

The top surface of an epithelial cell that borders an open space (lumen).

Single layer of cube-shaped cells; functions in secretion, absorption, and filtration in glands like the pancreas and kidneys.

Elongated cells with nuclei at the same level; main functions are absorption, protection, and secretion; often has microvilli and goblet cells.

Cells with varying heights, giving a layered appearance, but all touching the basement membrane; involved in absorption, secretion, and mucus movement.

Multi-layered, flat top cells (squamous); provides protection, with keratin making the skin waterproof.

Specialized layered epithelium with cells that can change shape depending on stretch; found in the urinary system.

Glands releasing hormones directly into the bloodstream, lacking ducts.

Glands with ducts, releasing substances onto epithelial surfaces (e.g., sweat, oil).

A thin supporting layer beneath epithelial tissues, not a type of tissue, but a supportive layer that holds the tissue together.
