The layers of the wall 10

  1. Rugae They flatten out as the stomach fills.
  2. Gastric pits The gastric glands open into the bottom of each pit.
  3. Mucosa The layer that makes the gastric juice.
  4. Gastric glands Their cells make acid, enzymes, mucus and hormones.
  5. Muscularis mucosae Part of the mucosa, not the main muscle wall.
  6. Submucosa Connective tissue with blood and lymph vessels.
  7. Oblique layer Only the stomach has this third layer; it helps churn the food.
  8. Circular layer Its fibres run round the stomach.
  9. Longitudinal layer Its fibres run the length of the stomach.
  10. Serosa The outermost layer of the stomach wall.

The cells of a gastric gland 4

  1. Mucous neck cells They make a thin, acidic mucus.
  2. Parietal cells They make hydrochloric acid and intrinsic factor.
  3. Chief cells They make pepsinogen, which acid turns into pepsin.
  4. Enteroendocrine cells They make hormones; G cells make gastrin.

How it works

The top drawing is a block cut from the stomach wall, from the folded lining to the outer covering. The bottom one enlarges a single gastric pit and its gland, with the cells that make the gastric juice.

The wall, then one gland

Numbers 1 to 10 are the wall: a fold of the lining, the pits and glands in it, the thin muscle under it, the submucosa, the three muscle layers and the serosa. Numbers 11 to 14 are the cells of one gland, from the neck down to the base. Each kind sits in its own zone, so the position in the gland tells you which cell it is.

  • The stomach has three muscle layers, not two: the extra oblique layer inside helps it churn food.

Questions and answers

What is a gastric pit?

A small dip in the stomach's lining. The gastric glands open into the bottom of each pit, and their juice flows up through it into the stomach.

What do parietal and chief cells make?

Parietal cells make hydrochloric acid and intrinsic factor. Chief cells make pepsinogen, which the acid turns into the protein-digesting enzyme pepsin.

What are the layers of the stomach wall?

From the inside out: the mucosa with its pits and glands, the submucosa, the muscularis with its oblique, circular and longitudinal layers, and the serosa.
