Capillaries, alveoli in the lungs, and glomeruli in the renal system are lined by simple squamous epithelial cells. Meanwhile, the skin, inside lining of the mouth, and the lining of the esophagus are made up of stratified squamous epithelial cells. How do the required functions of these tissues relate to the type of epithelial cells found there?.
Simple squamous epithelial cells allow for the passage of materials through using diffusion and filtration while also secreting substances for lubrication so in the alveoli, glomeruli and capillaries they filter and diffuse blood, nutrients, and waste. Stratified squamous epithelial cells are thicker protective cells that surround to ensure protection against harmful substances or external factors like cuts on the skin and inside of the mouth.
