      That’s a tough one.

      The most important one in my body right now is my liver, sorting through the absorbed bits of my dinner, processing any fats, making certain waste products easier to get rid of later, keeping me warm as it burns fuel to do these other tasks.

      In general? There’s a lot of organs you can live without (either part or all of them). You can be down a kidney and get on alright. Two thirds of your liver can be chopped out, and it’ll grow back. Many people have their large intestines removed for various reasons and can adapt to using colostomy bags and drinking more water (normally water is recovered from digested food by the large intestine). You can have a lung removed and live, but you won’t be running marathons. IF you’re missing your spleen, you’ll be a bit more prone to getting sick, but you’ll get on grand.
      You can’t yet live without a heart (artificial ones have a bit of a way to come). While it might seem that some people get on great without a brain, you really can’t live without one.

      Hi Killa,

      I would say the brain and the nervous system which is the connecting link between brain and other parts in the human body.
      The human nervous system is responsible for coordinating every movement or action your body takes. The nervous system is responsible for every function of the human body. In order for your heart to beat, your lungs to breath and your feet to walk your nervous system has to be functioning properly.
