Squamous epithelium is specialized for rapid diffusion because it is a single layer of flat cells, creating a very thin barrier as seen in the lungs.

Squamous epithelium is specialized for rapid diffusion due to its single layer of flat cells, creating a very thin barrier, as seen in the lining of the lungs.

Front Draw, label and annotate diagram to show how squamous epithelium is specialised for its function.
Back Squamous epithelium:
  • Made up of specialised squamous epithelial cells
  • Very thin bc it is one cell thick & the cells are flat - small diffusion distance
  • Its present when rapid diff. across a surface is essential (lining of lungs)
