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.

it is lined by the oral mucosa which has stratified squamous epithelium that protects the mouth from abrasion during ingestion of food.
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.
It is true that bones are covered and lined by a protective tissue called periosteum. The inner layer is made up mostly of osteoclasts and osteoblasts.
The urinary bladder and ureters are lined with transitional epithelium. This tissue allows the bladder to stretch when full and contract when empty. It looks like cuboidal epithelium when the bladder is contracted, and like stratified epithelium when distended.
Bones give support and structure because of hard mineral deposits they have, the bladder is made up of stretchable transitional tissue so that it can expand, Mucosa membranes are lined with epithelium which helps with absorption.

Natural ones are called orifices. Artificial ones are called stomas.

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.

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.
Both the human and grasshopper respiratory systems have structures called trachea that are lined with epithelial cells.
