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: -The brain stem is the lower part of the brain that’s connected to the spinal cord (part of the central nervous system in the spinal column). The brain stem is responsible for regulating most of the body’s automatic functions that are essential for life. These include: breathing.

Detailed explanation-3: -The respiratory center is located in the medulla oblongata and is involved in the minute-to-minute control of breathing.

Detailed explanation-4: -The apneustic (stimulating) and pnuemotaxic (limiting) centers of the pons work together to control rate of breathing. The medulla sends signals to the muscles that initiate inspiration and expiration and controls nonrespiratory air movement reflexes, like coughing and sneezing.
