Ciliated columnar epithelium moves mucus and other substances via cilia and is found in the upper respiratory tract, the Fallopian tubes, the uterus, and the central part of the spinal cord .They are the primary target of infection for common cold viruses such as coronaviruses, influenza virus and rhinoviruses.
A simple squamous epithelium is a single layer of flat cells in contact with the basal lamina (one of the two layers of the basement membrane) of the epithelium. This type of epithelium is often permeable and occurs where small molecules pass quickly through membranes via filtration or diffusion. Simple squamous epithelia are found in capillaries, alveoli, glomeruli, and other tissues where rapid diffusion is required. Cells are flat with flattened/rounded nucleus. It is also called pavement epithelium due to its tile-like appearance.
