Why Do Humans Vomit So Much? MinuteEarth

In an effort to protect us from getting killed by something we’ve ingested, our brain’s vomit control center processes a lot of information from several different places … and sometimes is a little overly cautious. LEARN MORE To learn more about this topic, start your googling with these keywords: Emesis: The act of vomiting Vomiting: The oral eviction of gastrointestinal contents due to contractions in the gut and stomach. Nausea: A diffuse sensation of uneasiness and discomfort often felt as the need to vomit. Vomiting Center: An area in the brain’s medulla oblongata that initiates and controls emesis. Chemoreceptor Trigger Zone: An area in the area postrema of the medulla oblongata that is sensitive to certain toxic chemicals in the blood. Nucleus Tractus Solitarius: A region in the medulla oblongata that receives input from the cardiovascular, respiratory and GI systems. Vagus Nerve: A cranial nerve that regulates internal organ functions, including vomiting. Vestibular System: A Sensory system that provides our brain with information about motion, head position, and spatial positioning for balance.
