How Do You Spell OXYNTIC CELL?

1. Oxyntic cell is a term used in biology to refer to a specialized type of cell found in the gastric glands of the stomach lining. Also known as parietal cells, oxyntic cells are primarily responsible for the secretion of hydrochloric acid (HCl) and intrinsic factor.

   The main function of oxyntic cells is to produce and secrete HCl, which is essential for the digestion and breakdown of food proteins. HCl helps maintain the highly acidic environment of the stomach, aiding in the activation of pepsinogen, an enzyme that breaks down proteins into smaller peptides.

   In addition to HCl, oxyntic cells also secrete intrinsic factor, a glycoprotein that plays a crucial role in the absorption of vitamin B12 in the small intestine. The secretion of intrinsic factor by these cells is crucial for the proper functioning of the gastrointestinal system and the prevention of vitamin B12 deficiency.

   Oxyntic cells are characterized by their large size and cytoplasmic canaliculi, which are invaginated membrane structures that increase the surface area for HCl secretion. They are typically located in the middle and lower regions of the gastric glands, surrounded by other types of cells such as chief cells and mucous cells.

   Overall, oxyntic cells play a vital role in the digestive process by secreting hydrochloric acid and intrinsic factor, ensuring proper protein digestion and vitamin B12 absorption, respectively.

Common Misspellings for OXYNTIC CELL

The word "oxyntic" is derived from the Greek word "oxys" meaning "acid", and "osteōn" meaning "bone". The term refers to cells that are found in the lining of the stomach and are responsible for producing hydrochloric acid, essential for the digestion of food.
