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.
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 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. Its release is stimulated by peptides in the lumen of the stomach.
  • What makes mucus?

    It's made by cells in membranes that run from your nose to your lungs. It's a form of mucus produced by the lower airways — not by the nose and sinuses — in response to inflammation. You may not notice phlegm unless you cough it up as a symptom of bronchitis or pneumonia.
  • What secretes HCL?

    The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.
B.

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 secretes mucus in the lungs?

    Mucus is secreted from two distinct areas within the lung tissue. In the surface epithelium, which is part of the tissue lining of the airways, there are mucus-producing cells called goblet cells. The connective tissue layer beneath the mucosal epithelium contains seromucous glands which also produce mucus.
  • What is phlegm made out of?

    Phlegm /ˈfl?m/ (Greek: φλέγμα "inflammation, humour caused by heat") is a liquid secreted by the mucous membranes of mammals. Its definition is limited to the mucus produced by the respiratory system, excluding that from the nasal passages, and particularly that which is expelled by coughing (sputum).
  • What is a respiratory secretions?

    Respiratory Secretions. Problems related to respiratory secretions can be caused by infection or aspiration, or by pooling of normal oropharyngeal secretions in a patient who is weak or unable to swallow or cough effectively (for instance in motor neurone disease) or who has a reduced state of consciousness.
C.

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 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 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.
  • 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.
