What is the most complex organ in the human body?
Undoubtedly, most of us will think of the brain.
Powered by energy-rich glucose and oxygen through the blood circulatory system, the brain is one of the biggest and most complex organs in our body.
This amazing organ, physically soft with a spongy mixture of protein and fat, weighs only approximately 2% of our total body weight, but utilises about a fifth of our energy!
The brain is composed of more than a hundred billion brain cells, which are made up of neurons and glia that communicate in trillions of connections known as synapses.
These unique neurons are nerve cells that conduct electrical impulses.
Meanwhile, glia cells provide structural protection and nutritional support for the neurons.
