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.
A.

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.
  • What tissue lines the small bronchioles?

    Most of the respiratory passageways, from the nasal cavity through the bronchi, are lined by ciliated, pseudostratified columnar epithelium with goblet cells. Bronchioles are lined by simple cuboidal epithelium. (Lung alveoli, in contrast, are lined by very thin simple squamous epithelium.)
  • What cells form the mucus?

    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.
  • What is the role of the mucus in the respiratory system?

    The major passages and structures of the upper respiratory tract include the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx). The respiratory system is lined with a mucous membrane that secretes mucus. The mucus traps smaller particles like pollen or smoke.
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 do D cells secrete?

    Alpha cells (A cells) secrete the hormone glucagon. Beta cells (B cells) produce insulin and are the most abundant of the islet cells. Delta cells (D cells) secrete the hormone somatostatin, which is also produced by a number of other endocrine cells in the body.
  • What cells secrete Pepsinogen?

    Proteases: Pepsinogen, an inactive zymogen, is secreted into gastric juice from both mucous cells and chief cells. Once secreted, pepsinogen is activated by stomach acid into the active protease pepsin, which is largely responsible for the stomach's ability to initiate digestion of proteins.
  • What are the chief cells of the parathyroid?

    Parathyroid chief cells (also called parathyroid principal cells or simply parathyroid cells) are one of the two cell types of the parathyroid glands, along with oxyphil cells. The chief cells are much more prevalent in the parathyroid gland than the oxyphil cells.
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.
  • 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.
  • 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).
  • 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.
