Stomach

J-shaped muscular organ in the epigastrium; length 25–30 cm, capacity 1–4 L. Secretes HCl (parietal cells, H⁺/K⁺-ATPase), pepsinogen (chief cells), intrinsic factor, mucus, and gastrin (G cells). Three-phase acid regulation; gastric mucosal barrier relies on prostaglandins.

Also known as: ventriculus, gaster, gastric, fundus, antrum, pylorus, cardia
