While the CTZ detects emetic substances, the vomiting center is the central hub that coordinates the physical act of vomiting. Located within the medulla, the vomiting center receives signals from the CTZ and integrates them with inputs from other regions, such as the vestibular system and gastrointestinal tract. It then orchestrates the complex sequence of events that result in emesis. Although distinct in function, the CTZ and vomiting center work together to protect the body from ingested toxins.
