Pronunciation: [pˈɛptɪk sˈɛlz] (IPA) 
The correct spelling of the word "peptic cells" is /ˈpɛptɪk sɛlz/. The first syllable "pep" is pronounced with a short e sound, followed by the long e sound in "tic". The "c" in "cell" is pronounced as /s/ because it is followed by an "e" which makes the letter "c" have the sound of /s/. "Peptic cells" refer to cells in the lining of the stomach that secrete digestive enzymes. It is a crucial part of the digestive process.
Peptic cells, also known as peptic cells of the gastric glands, refer to a specific type of cells present in the stomach lining. These cells are primarily responsible for producing various gastric secretions involved in the process of digestion.
In the human stomach, the mucosa lining contains millions of tiny gastric pits, within which lie several specialized cells, including the peptic cells. These cells are mainly found in the gastric glands of the stomach, particularly in the middle and lower regions.
Peptic cells are responsible for the synthesis and secretion of gastric juices, which are vital for the breakdown of food in the stomach. These secretions primarily consist of pepsinogen, an inactive precursor of the enzyme pepsin, as well as hydrochloric acid (HCl). Once released into the stomach, pepsinogen is enzymatically converted to pepsin by the acidic conditions created by the HCl. Pepsin is crucial for the initial digestion of proteins into smaller peptides.
Furthermore, peptic cells also secrete intrinsic factor, a glycoprotein necessary for the absorption of vitamin B12 in the small intestine. This helps prevent vitamin B12 deficiency, which can lead to anemia and other health issues.
Overall, peptic cells are integral to the digestive process, contributing to the breakdown of proteins and absorption of essential nutrients in the stomach.
Chief or central cells, columnar or polyhedral cells of the gastric glands, producing pepsin; distinguished from oxyntic cells.
