Brain cells
Controlling essential body functions like heartbeat and breathing.
Depressants slow bodily functions such as breathing and heartbeat pace.
The brain stem, also called the central brain or primitive brain is responsible for the basic functions such as breathing and heartbeat.
BRAINSTEM The medulla (located in the lower half of the brainstem).
it is responsible for vial life functions such as breathing heartbeat and blood pressure it is the most simple part of the human brain
The the lower part of the brain stem - medulla controls the heartbeat and breathing and other non-voluntary functions.
The medulla oblongata controls heart rate and respiration.Controlling essential body functions like heartbeat and breathing.
The part of the brain stem that controls heartbeat and breathing is called the medulla.
Since it controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it. But the rest of the brain is obviously capable of some remarkable feats, with one part able to compensate for deficiencies in another.
Breathing, digestion and heartbeat are all considered automatic body functions, because you don't have to think about them. You can hold your breath, or hyperventilate, but you don't have to "remember" to breathe.
