The Human Body System's Components: Facts

The Human Body System's Components: Facts The human body is a remarkable biological machine with over 100 trillion cells, 206 bones, 320 pairs of muscles, and 5 vital organs. These systems work together to allow for life, movement, cognitive function, growth, repair, reproduction, and more. The average height of an adult human is about five to six feet tall and they can get able to stand erect and walk on two feet. The human brain is the central command system for the whole body. It's a mass of about one hundred and eighty billion neurons, each with multiple synapses. These create a network of over 100 trillion connections. Tiny electrical currents and chemical messengers send information around the brain at 268 miles per hour. There's enough electrical current in your brain to power an LED light bulb.
