The Brain — Mission Control

Your brain is the boss of your entire body! It sits inside your skull, protected by hard bone. It is about the size of two fists together and weighs about 3 pounds. Your brain controls everything — thinking, feeling, remembering, dreaming, talking, and moving. It processes information from your five senses. It keeps your heart beating and your lungs breathing. It is the most complex and amazing organ in your whole body!
