oa SA Pharmacist's Assistant - Nausea and vomiting : gastrointestinal tract



Nausea is the unpleasant sensation associated with the urge to vomit. Vomiting is the forcing of the contents of the stomach up through the oesophagus and out of the mouth. Nausea and vomiting generally act as protective reflexes against the absorption of toxins, but can occur as result of a variety of other stimuli. The vomiting centre, located in the brain, initiates the vomiting reflex once it has been activated.
