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.

Simple columnar epithelium cells line the stomach. These cells also line the small intestine and the large intestine. They are uni-layered and are of two types - ciliated and non-ciliated.

Natural ones are called orifices. Artificial ones are called stomas.
Yes, the mouth is lined with a type of serous membrane called oral mucosa, which serves to protect and lubricate the oral cavity.

The walls of the respiratory tract consist of three main layers: the mucosa, submucosa, and adventitia. The mucosa is the innermost layer, lined with epithelial cells and containing mucus-secreting glands to trap particles and pathogens. The submucosa lies beneath the mucosa and contains connective tissue, blood vessels, and additional glands. The adventitia is the outermost layer, composed of connective tissue that provides structural support and connects the respiratory tract to surrounding tissues.
The gastrointestinal (GI) mucosa is adapted for absorption and secretion due to its large surface area lined with specialized cells like enterocytes, goblet cells, and enteroendocrine cells. These cells facilitate the absorption of nutrients and water while secreting enzymes, mucus, and hormones for digestive processes.
