Human brain

The human brain is the center of the central nervous system in humans as well as the primary control center for the peripheral nervous system.

The brain controls "lower" or involuntary activities such as heartbeat, respiration, and digestion - these are known as autonomic functions.

The brain also controls "higher" order, conscious activities, such as thought, reasoning, and abstraction.
