Final answer:
The term 'emesis' is commonly used in the medical field to describe the act of vomiting. Emesis can result from various irritants to the digestive tract, including flu viruses, leading to stomach contents being expelled through the mouth. There might be a typo error in option A. It is Emesis not Emess, therefore, the correct answer is option A. Emess.
Step-by-step explanation:
The medical term commonly used in place of the word vomit is emesis. Emesis describes the process of expelling the contents of the stomach through the mouth, and it can be caused by various irritants that affect the digestive tract. These irritants might include viruses, bacteria, strong emotions, disturbing sights, and food poisoning. The act of vomiting is controlled by the medulla, which regulates the forceful contractions of the stomach muscles during emesis.
If a student comes down with the flu, they might experience emesis as one of the symptoms. This is because the flu virus can act as an irritant to the digestive system, instigating the body's response to remove the irritant through vomiting.
