Vomiting primarily involves the digestive system, specifically the stomach and esophagus, as well as the central nervous system. The process is coordinated by the vomiting center in the brain, which receives signals from the gastrointestinal tract and other parts of the body indicating nausea or irritation. Muscular contractions in the stomach and diaphragm, along with relaxation of the esophageal sphincter, facilitate the expulsion of contents. Additionally, the autonomic nervous system regulates the involuntary aspects of this reflex.
