forceful expulsion of stomach contents through the mouth
Vomiting, also known as emesis, is the forceful expulsion of stomach contents through the mouth. It is often a reflex response to irritants in the stomach or digestive tract, but can also be triggered by various factors such as infections, motion sickness, pregnancy, or certain medical conditions. This process involves a complex coordination of the gastrointestinal tract, abdominal muscles, and the central nervous system.
