Vomiting 

Motion sickness, also called seasickness, carsickness, airsickness or space sickness, depending on what one has been traveling in, is a condition in which the endolymph (the fluid found in the semicircular canals of the inner ears) becomes 'stirred up', causing confusion between the difference between apparent perceived movement (none or very little), and actual movement. It can result from lying in the berth of a rolling boat without being able to see the outside. ...

Vomiting (or emesis) is the forceful expulsion of the contents of one's stomach through the mouth. Although it probably evolved as a mechanism for expelling ingested poisons, vomiting may result from many causes not related to poisoning, ranging from gastritis to brain tumors. The feeling that one is about to vomit is called nausea. It usually, but not necessarily, precedes vomiting, nor does it always lead to vomiting. Antiemetics are sometimes necessary to suppress nausea and vomiting.
