Part of the brain concerned with life support?

The part of the brain primarily responsible for life support functions is the brainstem, which includes the medulla oblongata, pons, and midbrain. The medulla oblongata regulates vital autonomic functions such as breathing, heart rate, and blood pressure. It acts as a critical pathway for communication between the brain and the spinal cord, ensuring that essential bodily functions are maintained. Disruption to the brainstem can severely impact survival.
