There are many types of cells in the stomach that help with the digestion of food These cells produce a thick coating of mucus, that protects the gastric mucosa from acid and enzymes in the lumen. Here are their names, functions, and locations.

In this article, we’ll explore the stomach anatomy, its internal and external parts, and how its blood and nerves work together The lining epithelium of the stomach, and gastric pits is entirely made up of mucous columnar cells A complete diagram of the human stomach highlighting its key parts and their functions for easy learning

The stomach is located in the upper abdomen, mostly under the lower ribs on the left side.

Parietal cells —located primarily in the middle region of the gastric glands are parietal cells, which are among the most highly differentiated of the body’s epithelial cells. Secrete pepsin, a proteolytic enzyme There are differences in the distribution of these cell types among regions of the stomach—for example, parietal cells are abundant in the glands of the body, but virtually absent in pyloric glands. Gastric pits and gastric glands are made up of the same 5 cell types

Mucous neck cells, stem cells, parietal (oxyntic) cells, chief (zymogenic) cells and enteroendocrine cells. These glands are narrow tubules composed of three major cell types Zymogenic, parietal, and mucous neck cells At the base of the gland are the zymogenic (chief) cells, which are thought to produce the enzymes pepsin and rennin.

The products of the endocrine cells are secreted directly into the bloodstream and are not a part of the gastric juice.

Parietal cells (also called oxyntic cells) are the stomach epithelium cells which secrete gastric acid Parietal cells produce gastric acid (hydrochloric acid) in response to histamine (via h2.
