Diagram showing parts of the stomach. The human stomach can be divided into four sections, beginning at the cardia followed by the fundus, the body and the pylorus. [8] [9] The gastric cardia is where the contents of the esophagus empty from the gastroesophageal sphincter into the cardiac orifice, the opening into the gastric cardia.
What you'll notice about a lot of the emotions that people feel in their stomach ( butterflies, the gutwrench, the knot) is that they're all different ways of experiencing the same emotion: stress.
The stomach is a distensible organ and can normally expand to hold about one litre of food. [22] This expansion is enabled by a series of gastric folds in the inner walls of the stomach. The stomach of a newborn baby will only be able to expand to retain about 30 ml.
The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products. The GI tract is composed of the alimentary canal, that runs from the mouth to the anus, as well as the associated glands, chemicals, hormones, and enzymes that assist in digestion.
In human anatomy, the intestine (bowel or gut; Greek: éntera) is the segment of the gastrointestinal tract extending from the pyloric sphincter of the stomach to the anus and as in other mammals, consists of two segments: the small intestine and the large intestine.
This allows the stomach to expand, therefore increasing the volume of the stomach without increasing pressure. [2] They also provide the stomach with an increased surface area for nutrient absorption during digestion. [2] Gastric folds may be seen during esophagogastroduodenoscopy or in radiological studies.

Stomach, a concept from traditional Chinese medicine as distinct from the Western medical concept of stomach, is more a way of describing a set of interrelated parts than an anatomical organ. The Stomach and its paired organ, the Spleen , are associated with the element of earth and the emotions of anxiety and stress.
