esophagus
Every system that has an outside opening produces mucous. This includes the respiratory, urinary, digestive and urogenital systems. Also the lining of the eye produces mucous. This substance keeps the membranes moist and prevents them from drying out.

Natural ones are called orifices. Artificial ones are called stomas.
The walls of the vagina are lined with a mucous membrane called vaginal epithelium. This epithelium is non-keratinized stratified squamous epithelium, which helps to protect the underlying tissues and maintain the pH and moisture balance of the vagina. The vaginal walls also contain elastic connective tissue and muscle fibers.

The cell that might be used to help the stomach digest is called trypsin. Also is do to protection by the stomach mucosa that is resistant to the stomach digesting itself. The stomach is lined with dense layers of epithelial cells.
it is lined by the oral mucosa which has stratified squamous epithelium that protects the mouth from abrasion during ingestion of food.
Organ Structure Larynx - made up of cartilage- contains the vocal cords; two highly elastic folds Trachea - a hollow tube surrounded by tough, flexible C-shaped cartilage rings- lined with cilia - lined with mucus secreting cells Lung - composed of the bronchi, bronchioles and alveoli
Yes it is true that epithelial cells may have cilia or processes called microvilli on their surfaces. The digestive tract is not lined internally mainly with stratified cuboidal cells.
