ANATOMY

Detailed explanation-1: -The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.

Detailed explanation-2: -Just as our heartbeat is controlled by pacemaker cells in the heart, our breathing is regulated by a cluster of a few thousand cells in the brainstem known as the preBötzinger Complex, or preBötC. Discovered in 1991, these cells are the center of breathing regulation.

Detailed explanation-3: -Final Answer: Medulla oblongata of the brain controls breathing.

Detailed explanation-4: -It is responsible for many vital functions of life, such as breathing, consciousness, blood pressure, heart rate, and sleep. The brainstem contains many critical collections of white and grey matter. The grey matter within the brainstem consists of nerve cell bodies and forms many important brainstem nuclei.
