Explanation: 

Detailed explanation-1: -Emesis, along with diarrhea, helps rid the gastrointestinal tract of dangerous ingested toxins.

Detailed explanation-2: -Neurotransmitters such as histamine or Ach are also released to the CTZ, which itself can releases chemicals such as dopamine and serotonin (5HT) that go on to stimulate the vomiting centre, which releases Ach, which then leads to the feelings of nausea and actions of vomiting.

Detailed explanation-3: -As your body prepares to vomit, the major muscles in between the neck and abdomen – the diaphragm, chest wall and the abdominal muscles – all contract at the same time. This puts pressure on the stomach, forcing the contents in the stomach up the throat and through your mouth.
