•  Skin: The outer layer of the skin is lined with squamous epithelium.
• Oesophagus: Squamous epithelium lines the oesophagus to protect against abrasion from food.

• Squamous Epithelium: Found in areas subject to wear and tear, like the skin, mouth, and oesophagus.
• Cuboidal Epithelium: Found in kidney tubules, aiding in absorption and secretion.
