Cells that make up the pyloric antrum secrete mucus and a number of hormones, including the majority of the stimulatory hormone, gastrin. The much larger glands of the fundus and body of the stomach, the site of most chemical digestion, produce most of the gastric secretions. These glands ...
The parietal cells produce rennin that coagulates milk protein, intrinsic factor for vitamin B12 absorption, and hydrogen chloride (HCl). The low luminal pH destroys many ingested pathogens, but there is a resident bacterial flora that cannot be cultured by conventional methods. Chief cells produce...
Parietal cells secrete acid to control stomach pH. Enteroendocrine cells secrete hormones into the underlying lamina propria such as gastrin that promotes acid secretion. Finally, as a luminal chemosensing cell type, gastric tuft cells project apical processes into the lumen and also produce secreted ...
Which stomach cells produce pepsinogen?Stomach:Our stomach is a J-shaped organ that holds and digests food. There are several kinds of cells that make up the stomach; each cell performs a specific function. The stomach also releases digestive juices and enzymes that break food down....
Step-by-Step Solution:1. Identify the Cells in the Stomach: The stomach contains various types of cells that perform different functions. Among these cells, some are responsible for secreting hydrochloric ac
The mucosa is lined with numerous glands containing specialized cells that produce various secretions: e.g., parietal cells, which secrete gastric acid and intrinsic factor, and gastric chief cells, which secrete pepsinogen. Acetylcholine (ACh), gastrin, and histamine are the main stimulators of ...
The HCl also kills most bacteria that may accompany the food. Chemical breakdown. Proteins are chemically broken down by the enzyme pepsin. Chief cells, as well as other stomach cells, are protected from self‐digestion because chief cells produce and secrete an inactive form of pepsin, ...
Pyloric stenosis:characterized by hypertrophy and hyperplasia of the pyloric sphincter in the first months of life. Pyloric stenosis is the most common cause of gastric outlet obstruction in infants. Clinical presentation includes postprandial vomiting that is nonbilious and forceful (often described as ...
Stomach acid, also called Gastric Acid, is made on demand when you eat via the parietal cells that line your stomach. Those parietal cells use various minerals to help make stomach acid–the latter which is mainly composed of hydrochloric acid, potassium and sodium, and will usually have a ...
2021: Lab-grown stomachs now produce acid as real In early December 2021, scientists at Cincinnati Children's Hospital announced the successful creation of a stomach organoid so complex that it has separate glands and nerve cells that can control smooth muscle contractions. This achievement is a ...
