2: The brain is the most complex organ in the body

The brain consists of complex networks of billions of neurons called cell neurons and other kinds of cells, all protected by the skull. A typical brain weighs only about 3 pounds, but it is the source of the highest quality and makes you self. Neurons in the brain and spinal cord are part of the nervous system and function as "the center of command" of the body.

As for sleep, the brain becomes active. In fact, when sleeping or waking up, the brain needs 20% of the heart to output fresh blood, 20% of blood oxygen and glucose to keep blood moving. Glucose is the sugar which is the main fuel of our brain.

The brain produces enough power to power a 40-watt bulb for 24 hours. For human organs slightly larger than softball, this is a big energy.

It is the most complex organ in the body, it controls most of the process of keeping us alive - it makes us humans. Tactile, olfactive, tasteful, visual and sound - the brain accepts input from the sensory system. In a matter of seconds, this information was classified, selected, processed, integrated and coordinated by the brain. It then sends instructions to other parts of the body. Even though we review previous experiences and review memories and ideas to find clarity and better understanding, we still flash the real consciousness in a matter of seconds. Shankar Vendantam is a NPR podcast with the same name as his book "Hidden Brain", explaining the concept using dolphins.

The brain is a very complex organ. The brain is the most important organ in your body. I can not do anything without a brain. Every little thought or small muscle movement comes from my brain. The brain controls what people do and how they feel about something. - Cancer caused great sadness in the United States.
