The brain is a organ. The brain is the organ that receives messages from the six senses; the touch sense, the seeing sense, the hearing sense, the smelling sense and the tasting senses. If you are asking 'Is the brain the largest organ?' Well, no. The largest organ is not the brain, or the chest, or the stomach. It is the skin.
like say this if you put your hand on top of a burning candle the heat will burn your hand and your nerve system will feel it and then it will send a signal up from your hand to your spinal cord and then the massage from your spinal cord will get sent up to your brain telling it what has happened and then the brain will send another massage down our spinal cord into your hand which will tell your muscle to lift up your arm away from the burning candle
