Why is there an increase in saliva production before vomiting?

Saliva production often increases before vomiting as a natural protective mechanism of the body. When the stomach senses irritation or a potential threat, such as toxins or a viral infection, it triggers the production of excess saliva. This increase in saliva helps to lubricate the digestive tract, making it easier for the contents of the stomach to pass through and be expelled. Additionally, saliva contains digestive enzymes that can help neutralize the acid in the stomach, reducing potential damage to the esophagus when vomiting occurs. Therefore, increased saliva production serves as a defense mechanism to protect the body during the process of vomiting.
