22.14B: Gastric Phase - Medicine LibreTexts
The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity. About two-thirds of gastric secretion occurs during this phase. Ingested food stimulates gastric activity in two ways: by stretching the stomach and by raising the pH of its contents.

The gastric phase of secretion lasts 3 to 4 hours, and is set in motion by local neural and hormonal mechanisms triggered by the entry of food into the stomach. For example, when your sushi reaches the stomach, it creates distention that activates the stretch receptors.

Stomach Anatomy: Complete Guide with Parts, Names & Diagram
2024年12月31日 · The gastric glands are tiny, tube-like structures found in the inner lining of the stomach. These glands are essential for digestion, as they produce various substances needed to break down food. They start at small openings in the stomach lining called gastric pits, which are part of the stomach’s mucous layer.
Phases of Digestion – Boundless Anatomy and Physiology
gastric phase: The second phase of digestion that follows mastication (chewing) and takes place in the stomach. The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity. About two-thirds of gastric secretion occurs during this phase.

Gastric secretion occurs in three phases: cephalic, gastric, and intestinal. During each phase, the secretion of gastric juice can be stimulated or inhibited. The cephalic phase (reflex phase) of gastric secretion, which is relatively brief, takes place before food enters the stomach.
The Stomach | Anatomy and Physiology II - Lumen Learning
There are four main regions in the stomach: the cardia, fundus, body, and pylorus. The cardia (or cardiac region) is the point where the esophagus connects to the stomach and through which food passes into the stomach. Located inferior to the diaphragm, above and to the left of the cardia, is the dome-shaped fundus.

4 天之前 · The main exocrine product of the stomach is gastric juice--- a mixture of mucus, hydrochloric acid, and digestive enzymes. Gastric juice is mixed with food in the stomach to promote digestion. Specialized exocrine cells of the mucosa known as mucous cells secrete mucus into the lumen of the stomach and into the gastric pits. This mucus spreads ...

2023年7月17日 · The wall of the stomach consists of four different tissue layers; mucosal layer, submucosa, muscularis externa, and adventitia/serosa. The gastric mucosal layer further subdivides into three layers; the surface epithelium, a connective tissue layer called the lamina propria, and the muscularis mucosa.
