stomach

1 of 2

noun

stom·​ach ˈstə-mək How to pronounce stomach (audio)
-mik
1
a(1)
: a saclike expansion of the digestive tract of a vertebrate that is located between the esophagus and duodenum and typically consists of a simple often curved sac with an outer serous covering, a strong muscular wall that contracts rhythmically, and an inner mucous membrane lining that contains gastric glands

Note: In humans, the stomach is located in the upper abdomen, below the esophagus and above the small intestine. It functions mainly to partially digest food by grinding and mixing it with gastric secretions (such as hydrochloric acid and pepsin). Mucus is also secreted to protect the stomach lining from damage by the acidic environment. Once ingested food has been partially digested by the stomach, it is discharged through the pylorus into the duodenum in the form of the semifluid chyme for further digestion.
