what part of the brain controls heart rate and breathing

The medulla oblongata, which is located at the bottom of the brainstem, is responsible for controlling important bodily functions such as breathing, heart rate, blood pressure, and digestion. It is also responsible for reflexive activities such as sneezing, vomiting, coughing, and swallowing. The medulla oblongata is where the cardiovascular and respiratory systems link together into a united system that controls heart rate, breathing, blood pressure, and more. Therefore, the medulla oblongata is the part of the brain that controls heart rate and breathing.
