The stomach is an important organ in the digestive system. After food has been chewed in the mouth and swallowed, it enters the stomach via the oesophagus. The stomach produces strong acid. This kills many harmful microorganisms that might have been swallowed along with the food. It also contains special chemicals called enzymes.

The stomach is a muscular, hollow organ in the gastrointestinal tract of humans and many other animals, including several invertebrates. The stomach has a dilated structure and functions as a vital digestive organ. In the digestive system the stomach is involved in the second phase of digestion, following mastication (chewing).

Conditions and diseases. The stomach can have many different conditions and diseases that can cause pain, discomfort, digestion problems and even death. One of the most common stomach problems is upset stomach or dyspepsia.

Stomach. When the stomach is empty, the inside has small folds called rugae. Rugae allow the stomach to expand to accommodate large meals. They also grip the food inside the stomach to help physically break it down. The average stomach can hold about 1.5 gallons of food and liquid at maximum capacity.

Picture of Stomach. The stomach is the muscular organ that receives food and drink after they travel down the esophagus. The separation between the esophagus and the stomach is a valve called the lower esophageal sphincter. The stomach lining contains muscular folds called rugae.

The enzymes in the mouth and stomach include amylase, lipase and pepsin — and each is responsible for helping to start the digestion process for carbohydrates, fat and protein. It Starts in the Mouth

The function of stomach enzymes is to break down foods into simpler nutrients, which can then be absorbed or further digested within the gut. Pepsin is the active form of pepsinogen which is secreted by the chief cells in the stomach wall. Pepsinogen is converted to pepsin by the action of stomach acid.

Unless you’re taking them in very high dosage, the risks for most enzyme supplements are pretty minimal. Digestive enzymes may trigger a number of side effects, including stomach pain, nausea, diarrhea, and vomiting. In addition, some people may experience allergic reactions to digestive enzymes.

Stomach Location (Anatomical Position), Parts and Pictures. The stomach is a hollow organ that lies between the esophagus (food pipe) and duodenum (small intestine). It is an expanded part of the gastrointestinal tract (gut) that plays an important role in the digestion of food. The churning of food and gastric acid secretion breaks down food…

The stomach is a muscular sac located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter.

It contains the cardiac sphincter, which is a thin ring of muscle that helps to prevent stomach contents from going back up into the esophagus. The fundus is the rounded area that lies to the left of the cardia and below the diaphragm. The body is the largest and main part of the stomach.

A number of diseases can involve the stomach lining. Like other cells, the epithelial cells in the stomach can become cancerous, causing the development of stomach cancers. The stomach lining can also become inflamed in a condition known as gastritis, or ulcerated.

It typically doesn’t cause much inflammation, but can lead to bleeding and ulcers in the lining of the stomach. What causes gastritis? Weakness in your stomach lining allows digestive juices to damage and inflame it, causing gastritis. Having a thin or damaged stomach lining raises your risk for gastritis.

The stomach lining has a number of types of epithelial cells, divided by type. Mucous cells generate the mucus which stands between the stomach lining and the acids of the stomach, creating a protective layer. Parietal sells secrete acid, while chief cells make enzymes used in digestion,…
