emetic reflex

The emetic reflex is a natural response the body uses to prevent harmful substances from entering the digestive system. When the brain detects toxins, irritation, or certain signals from the stomach or throat, it triggers this reflex—leading to nausea and the act of vomiting. Vomiting helps expel unwanted substances quickly, protecting the body from potential harm. It involves coordinated movements of the stomach, diaphragm, and abdominal muscles, controlled by the brain’s vomiting center, which processes signals from various parts of the body related to threat or irritation.
