The medulla oblongata
Explanation: By way of introduction, there are three components of the brainstem which consists of the medulla oblongata, pons, and midbrain.The medulla oblongata is the lower half of the brainstem. The medulla oblongata controls autonomic functions and connects the higher levels of the brain to the spinal cord. It is also responsible for regulating several basic functions of the autonomic nervous system, including:
i. Respiration: chemoreceptors
ii. Cardiac center: sympathetic system, parasympathetic system
iii. Vasomotor center: baroreceptors
