Squamous epithelial cells form the inner lining of urinary tract. These cells collect along the skin of penis and vagina. Whenever you pass out urine; these cells, present along the skin, also flow along.
There are three principal shapes of epithelial cell: squamous, columnar, and cuboidal. These can be arranged in a single layer of cells as simple epithelium, either squamous, columnar, cuboidal, pseudo-stratified columnar or in layers of two or more cells deep as stratified (layered), either squamous, columnar or cuboidal. All glands are made up of epithelial cells.
