Some of our internal body  parts work continuously  without  rest. Our brain,

          heart, lungs, stomach, liver, and kidneys, among other organs, work tirelessly

          to keep us alive. If any of these organs stop working we will die.

          Let’s study how these organs function.

                                                                                 Think &    Are  the  chest  and

          Brain

          The brain is located inside our head and is protected by the skull, a hard layer of

          bones. All our body functions are controlled by the brain.

          The brain receives signals from our sensory organs and

          sends information to other parts of the body. It stores

          information as messages. It helps us to think and learn
          new things.


          Our posture,  balance, and movements while  walking,

          running, or driving are also controlled by the brain.                                       Brain
