The lumen.
Skin, hair, nails, and the lining of organs such as the respiratory tract, gastrointestinal tract, and urinary tract are of epithelial origin. Epithelial cells serve as a protective barrier and have various functions depending on their location in the body.
The endoderm layer of embryonic tissue forms the lining of the digestive tract. It gives rise to the epithelial cells that make up the inner lining of the gastrointestinal system.
Epithelial cells can be found covering the surfaces of organs, glands, and tissues throughout the body. They form protective barriers and linings, such as the skin, inner lining of the digestive tract, and the respiratory system.
The lining of the entire digestive tract is called the mucosa. It makes what we call mucous.
Mucin is produced by goblet cells, specialized epithelial cells found in the lining of various organs such as the respiratory tract, gastrointestinal tract, and eyes. It helps protect and lubricate the surface of these organs.

Epithelial tissue lines the stomach, like most internal organs.

Goblet cells are typically found in the epithelial lining of the respiratory tract, gastrointestinal tract, and conjunctiva of the eye. These cells secrete mucus to protect and lubricate these tissues.
The epithelial tissues are found inside the mouth, in the esophagus, and in the rectum.
In the lining of the respiratory tract.
Mucin is produced by goblet cells, specialized epithelial cells found in the lining of various organs such as the respiratory tract, gastrointestinal tract, and eyes. It helps protect and lubricate the surface of these organs.
Epithelial tissue is found in lining or covering structures that are exposed to wear and tear like skin, respiratory tract, and gastrointestinal tract. Its main function is to provide protection against mechanical injury, pathogens, and chemical substances.
The lining of the digestive tract is an example of epithelial tissue. Epithelial tissue forms the protective layers that line cavities and surfaces throughout the body, including the gastrointestinal tract. In contrast, aponeuroses are fibrous connective tissues, and the larynx contains both cartilage and connective tissues, rather than being classified as epithelial.
A group of epithelial cells working together to line a cavity of the body is called an epithelium. Epithelial cells form tight junctions to create a barrier that protects underlying tissues and organs from damage or infection. These cells can be found lining various cavities in the body, such as the respiratory tract, gastrointestinal tract, and blood vessels.
