the ________ is a structure in the brain stem responsible for life-sustaining functions, such as breathing and heart rate.
The medulla oblongata is located in the lower portion of the brainstem. It is very important in things like heart rate and blood pressure. It's responsible for many reflexes in the body, or involuntarily controls, such as vomiting, sneezing, and coughing. A brain stem stroke happens when the brainâs blood supply is interrupted in this area. This type of stroke can result in death, since the damaged brain stem can no longer control the bodyâs vital functions.
