What cells secrete mucus in the respiratory system?

Nasal mucus is produced by the nasal mucosa; and mucus lining the airways (trachea, bronchus, bronchioles) is produced by specialized airway epithelial cells (goblet cells) and submucosal glands.
A.

What do mucous cells secrete?

Small pores called gastric pits contain many exocrine cells that secrete digestive enzymes and hydrochloric acid into the lumen, or hollow region, of the stomach. Mucous cells found throughout the stomach lining and gastric pits secrete mucus to protect the stomach from its own digestive secretions.
  • What is secreted by mucous cells?

    Mucus is composed of water, epithelial (surface) cells, dead leukocytes, mucin, and inorganic salts. Mucus is produced by mucous cells, which are frequently clustered into small glands located on the mucous membrane that lines virtually the entire digestive tract.
  • What are the secretion of Enteroendocrine cells?

    Enteroendocrine cells are cells found in the wall of the gut that secrete hormones that regulate numerous processes in the body, including controlling glucose levels, food intake, and stomach emptying.
  • How does the stomach protect itself from the acid?

    Your stomach protects itself from being digested by its own enzymes, or burnt by the corrosive hydrochloric acid, by secreting sticky, neutralising mucus that clings to the stomach walls. If this layer becomes damaged in any way it can result in painful and unpleasant stomach ulcers.
B.

What is secreted by chief cells?

The gastric chief cell (also known as a zymogenic cell or peptic cell) is a cell in the stomach that releases pepsinogen and chymosin. Pepsinogen is activated into the digestive enzyme pepsin when it comes in contact with acid produced by gastric parietal cells.
  • What is the function of G cells?

    In anatomy, the G cell (or γ-cell) is a type of cell in the stomach and duodenum that secretes gastrin. It works in conjunction with gastric chief cells and parietal cells. G cells are found deep within the pyloric glands of the stomach antrum, and occasionally in the pancreas and duodenum.
  • What secretes the hormone gastrin?

    Gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum, and the pancreas.
  • Is pancreatic juice endocrine or exocrine?

    Functioning as an exocrine gland, the pancreas excretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food. Functioning as an endocrine gland, the pancreas secretes the hormones insulin and glucagon to control blood sugar levels throughout the day.
C.

What does the mucosa secrete?

A mucous membrane or mucosa is a membrane that lines various cavities in the body and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. Some mucous membranes secrete mucus, a thick protective fluid.

  • What is an example of the mucous membrane?

    Examples of mucous membranes includes: lips, mouth, nasal passages, middle ear and the eustachian tube. Other mucous membranes include the lining of the digestive tract, the lining of the urogenital tract (including the urethra and vagina), the lining of the respiratory tract, and your eyes (conjunctival membranes).
