| textual definition |
An expanded region of the vertebrate alimentary tract that serves as a food storage compartment and digestive organ. A stomach is lined, in whole or in part by a glandular epithelium. 脊椎动物消化道的扩大区域，用作食物储藏室和消化器官。胃内衬全部或部分由腺上皮组成。 |

We restrict this to the vertebrate specific structure - see the grouping class 'food storage organ' for analogous structures in other species. Teleosts: Zebrafish is functionally stomach-less, but may retain ontogenic footprint. Although the precise shape and size of the stomach varies widely among different vertebrates, the relative positions of the oesophageal and duodenal openings remain relatively constant. As a result, the organ always curves somewhat to the left before curving back to meet the pyloric sphincter. However, lampreys, hagfishes, chimaeras, lungfishes, and some teleost fish have no stomach at all, with the oesophagus opening directly into the intestine. The gastric lining is usually divided into two regions, an anterior portion lined by fundic glands, and a posterior with pyloric glands. Cardiac glands are unique to mammals, and even then are absent in a number of species. The distributions of these glands vary between species, and do not always correspond with the same regions as in man. Furthermore, in many non-human mammals, a portion of the stomach anterior to the cardiac glands is lined with epithelium essentially identical to that of the oesophagus. Ruminants, in particular, have a complex stomach, the first three chambers of which are all lined with oesophageal mucosa 我们把这限制在脊椎动物的特定结构上--参见"食物贮藏器官"类中的其他物种的类似结构。硬骨鱼：斑马鱼在功能上无胃，但可能保留个体发育的足迹。虽然胃的精确形状和大小在不同的脊椎动物中变化很大，但是食管和十二指肠开口的相对位置保持相对恒定。结果，器官在向后弯曲以与幽门括约肌相遇之前，总是稍微向左弯曲。然而，文昌鱼、石斑鱼、文冠鱼、肺鱼和一些硬骨鱼根本没有胃，食管直接通入肠内。胃衬里通常分为两个区域，前部由胃底腺衬里，后部由幽门腺衬里。心脏腺体是哺乳动物特有的，甚至在许多物种中也不存在。这些腺体的分布因物种而异，并不总是与人类的相同区域相对应。此外，在许多非人哺乳动物中，心脏腺体前面的胃的一部分衬有基本上与食管的上皮相同的上皮。反刍动物尤其具有复杂的胃，其前三个腔室均衬有食管粘膜。 |

胃似乎有一个古老的起源。胃首先出现在鱼类系谱中。脊椎动物的脊索没有真正的胃，而软骨和硬骨鱼有。虽然大多数鱼确实有一个真正的胃，一些鱼类物种似乎已经第二次失去胃了。其余的脊椎动物谱系确实有一个真正的胃（至少在成年动物中），尽管胃的大小和形状有很大的变化。[well established][VHOG] It appears that the stomach has an ancient origin. The stomach first appears in the fish lineage. The prevertebrate chordates do not have a true stomach, whereas the cartilaginous and bony fish do. Although most fish do have a true stomach, some fish species appear to have lost the stomach secondarily. The remaining vertebrate lineages do have a true stomach (at least in the adult animal), although there is great variation in the size and shape of the stomach.[well established][VHOG] |

Portion of alimentary canal with increased circular and longitudinal smooth muscle. Bounded posteriorly by the pyloric sphincter. Mucosal lining has increased folding.[AAO] 部分消化道有增大的圆形和纵向的平滑肌。由幽门括约肌向后界定。粘膜衬里有增加的折叠。[AAO] |
