Anatomical terms of location

Standard anatomical terms of location deal unambiguously with the anatomy of animals, including humans.

All vertebrates (including humans) have the same basic body plan – they are strictly bilaterally symmetrical in early embryonic stages and largely bilaterally symmetrical in adulthood.[1] That is, they have mirror-image left and right halves if divided down the centre.[2] For these reasons, the basic directional terms can be considered to be those used in vertebrates. By extension, the same terms are used for many other (invertebrate) organisms as well.

Stomach

The stomach is a muscular, hollow, dilated part of the gastrointestinal tract that functions as an important organ in the digestive system. The stomach is present in many animals including vertebrates, echinoderms, insects (mid-gut), and molluscs. In humans and many other vertebrates it is involved in the second phase of digestion, following mastication (chewing).

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 into smaller particles and simpler compounds for further digestion and subsequent absorption in the small intestine. Certain nutrients and substances are also absorbed in the stomach.
