'''Lambung''' atau '''perut''' ({{lang-en|stomach}}; {{lang-nl|maag}}) atau ventrikulus berupa suatu kantong yang terletak di bawah sekat rongga badan.
Fungsi lambung secara umum adalah tempat di mana makanan dicerna dan sejumlah kecil sari-sari makanan diserap.

The lesser curvature of the human stomach is supplied by the [[right gastric artery]] inferiorly, and the [[left gastric artery]] superiorly, which also supplies the cardiac region. The greater curvature is supplied by the [[right gastroepiploic artery]] inferiorly and the [[left gastroepiploic artery]] superiorly. The fundus of the stomach, and also the upper portion of the greater curvature, is supplied by the short gastric artery which arises from the splenic artery.

==Development==
In early [[human embryogenesis]], the ventral part of the embryo abuts the [[yolk sac]]. During the second week of development, as the embryo grows, it begins to surround parts of the sac. The enveloped portions form the basis for the adult gastrointestinal tract.<ref name=LARSEN2009 /> The sac is surrounded by a network of [[vitelline arteries]]. Over time, these arteries consolidate into the three main arteries that supply the developing gastrointestinal tract: the [[celiac artery]], [[superior mesenteric artery]], and [[inferior mesenteric artery]]. The areas supplied by these arteries are used to define the [[midgut]], [[hindgut]] and [[foregut]].<ref name=LARSEN2009 /> The surrounded sac becomes the primitive gut. Sections of this gut begin to differentiate into the organs of the gastrointestinal tract, and the esophagus, and stomach form from the foregut.<ref name=LARSEN2009>{{cite book|author=Gary C.

Meskipun bentuk dan ukuran lambung berbeda di antara hewan-hewan [[vertebrata]], posisi relatif pintu esofagus dan duodenum tetap relatif konstan. Akibatnya, organ ini selalu agak melengkung ke kiri sebelum melengkung kembali untuk bertemu dengan ''pyloric sphincter''. Namun, [[:en:lamprey|''lamprey'']], [[:en:hagfish|''hagfish'']], ''[[chimaera]], [[:en:lungfish|lungfish]]'', dan sejumlah ikan [[:en:teleost|teleost]] tidak mempunyai lambung sama sekali, dengan esofagus langsung terbuka ke [[anus]]. Semua hewan ini mengkonsumsi makanan yang hanya membutuhkan sedikit tempat penyimpanan, atau tanpa dicerna terlebih dahulu dengan cairan lambung, atau keduanya.<ref name=VB>{{cite book |author=Romer, Alfred Sherwood|author2=Parsons, Thomas S.|year=1977 |title=The Vertebrate Body |url=https://archive.org/details/vertebratebody0000rome_a5a9|publisher=Holt-Saunders International |location= Philadelphia, PA|pages=

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 [[mammal]]s, 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 humans. 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. [[Ruminant]]s, in particular, have a complex stomach, the first three chambers of which are all lined with oesophageal mucosa.<ref name=VB/>
