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 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.
The duodenal mucosa is the innermost layer of the duodenum, which is the first part of the small intestine. It is lined with specialized epithelial cells that secrete digestive enzymes and mucus, facilitating the digestion and absorption of nutrients. The mucosa also contains villi and microvilli, which increase the surface area for nutrient absorption. Additionally, it plays a role in the secretion of hormones that regulate digestive processes.
