Simple squamous epithelium is a single layer of flattened cells, resembling a tiled floor. Found in areas where efficient diffusion or filtration is crucial, such as the lungs (alveoli) and blood vessels (endothelium), it facilitates easy substance exchange. With a thin structure, these cells optimize surface area for rapid diffusion. This tissue type is vital for functions like nutrient absorption and waste removal, showcasing the adaptability and specialization of epithelial tissues in maintaining homeostasis within the body.
