In fact, in 1991 scientists even took their research of the heart further when they decided over 40,000 sensory neurons in our heart, confirming the heart does have a mini brain. But the most surprising discovery is that the information flows more from the heart to the brain than viceversa, signaling to the fact that it might supersede the brain in hierarchy. This is probably related to the electromagnetic field which we have discovered surrounding our hearts.

We have come a long way from believing the heart is just a pump, haven’t we? One of such pioneers was Rudolph Steiner , a genius who was among the first to mention that the heart was a much more complex and powerful organ than just a pump.

He also founded Waldorf education, which is a popular child-centered philosophy for schooling. He also created a system of alternative medicine called anthroposophical medicine.

How long can you live with only one kidney?
6) Kidneys: Kidneys perform a few essential functions: They filter your blood, prevent the buildup of waste and extra fluid and produce hormones that help your body regulate its blood pressure, produce red blood cells and some other stuff, too. The good thing about kidneys is, it’s entirely possible to live a perfectly healthy life with just one. And even if you lose both, you can be put on dialysis, which draws waste out of the body, and recent research shows someone placed on dialysis at age 20 can expect to live for 16 to 18 years. It’s very far from ideal, but a lot longer than you’d live without a heart or brain.
What part of the body stores and recycles red blood cells?
8) Spleen : The spleen plays a part in your immune response: It stores and recycles red blood cells, and houses white ones. However, the spleen is fairly commonly removed as a result of trauma, and you can live comfortably without it, since the liver does a fine job of recycling red blood cells, and other parts of the lymphatic system are able to take over any immune functions that the spleen was previously handling.
What is the function of the liver?
4) Liver: The liver performs more than 500 life-sustaining functions, including filtering toxins (i.e., booze) from your blood, producing digestive enzymes, storing vitamins and minerals, regulating hormones and helping blood clot.

What is the function of the small intestine?
5) Small Intestines: The small intestines are what break down food from the stomach and absorb most of the nutrients that food provides. As the American Society of Transplantation explains, “Most people can live without a stomach or large intestine, but it is harder to live without a small intestine. When all or most of the small intestine has to be removed or stops working, nutrients must be put directly into the blood stream (intravenous or IV) in liquid form.” That essentially means you need to be hooked up to a drip feeder until you can get a transplant.
What organs are most important to the human body?

Because of that, in most of the world, a person is legally dead if they permanently lose all brain activity. Thanks to medical technology, like ventilators, your body could hypothetically be kept “alive” for some amount of time without a brain , but a lack of important hormones and an inability to regulate your temperature would eventually quash anything left working, too.
Why is the heart important?
2) Heart: The heart is almost as important as the brain, since it pumps blood, which carries oxygen and other important nutrients that every organ needs to stay healthy and work properly. Traditional wisdom says the brain typically suffers irreparable damage when someone goes without a heartbeat for more than 20 minutes. On the bright side, medical technology has done a better job of replacing hearts than brains: A 25-year-old from Michigan lived a whole 555 days without one at all, thanks to an artificial heart pumping in his chest.
Can you live without a stomach?
7) Stomach (and Large Intestines, aka Colon): As the American Society of Transplantation so kindly mentioned earlier, people can live without a stomach, despite how miserable that may sound. It’s sometimes surgically removed as a result of cancer or trauma — a teen in England, for example, had to have hers taken out after drinking a cocktail laced with liquid nitrogen — then the surgeons attach the oesophagus directly to the small intestines. If all goes well, you can eat a normal diet, accompanied by some supplements.
