Squamous epithelial tissue

• Squamous epithelial tissue is a lining tissue.
• This tissue is one cell thick and is made from flattened squamous epithelial cells.
• The thin, smooth, flat layer makes it the ideal location for diffusion to occur rapidly.
• Squamous epithelial tissue can be found in the alveoli in our lungs.
• The epithelium cells in the lungs can become damaged through smoking as the smoke is an irritant causing inflammation and scaring which produces more mucus.
• Damage to epithelium cells is associated with COPD.
