The appendix may be the most commonly known useless organ. Many years ago, the appendix may have helped people digest plants that were rich in cellulose, Gizmodo reported. While plant-eating vertebrates still rely on their appendix to help process plants, the organ is not part of the human digestive system.
It is found that although its function gets altered, there is no reduction in life expectancy observed. Hence the reproductive system could be the least important system in the body.
You'll be surprised as to how much you could lose and still live. You can still have a fairly normal life without one of your lungs, a kidney, your spleen, appendix, gall bladder, adenoids, tonsils, plus some of your lymph nodes, the fibula bones from each leg and six of your ribs.

That fluid and the tissues connecting them are called the interstitium (pronounced "inter-STISH-um"), and they're found throughout the body, both just below the skin and in the digestive, respiratory and urinary systems.
Liver, sort of
While you can't live without your liver, you can live with just part of it. Your liver is the only organ in your body that can regrow after parts of it have been removed or damaged. In fact, it can grow back to its full size in just months.

The brain and nerve cells require a constant supply of oxygen and will die within a few minutes, once you stop breathing. The next to go will be the heart, followed by the liver, then the kidneys and pancreas, which can last for about an hour. Skin, tendons, heart valves and corneas will still be alive after a day.
You can comfortably live without a spleen. This is because the liver plays a role in recycling red blood cells and their components. Similarly, other lymphoid tissues in the body help with the immune function of the spleen.
Vital Organs
The human body contains five organs that are considered vital for survival. They are the heart, brain, kidneys, liver, and lungs.
The brain is perhaps the most important organ in the body. While many organs are critical to our survival, the brain contains the self.
Major organs that can fail include the brain, heart, lungs, kidneys, liver and intestines (gut). If one of these organs stops working, the patient will not be able to survive without the help of very strong medicines and/or machines. WHO IS AT RISK FOR ORGAN FAILURE?
Researchers at Vanderbilt University in Nashville, Tennessee, have found that while you are asleep, the only body part that remains active is the ear.
When we are born, our organs are fully developed and functioning. Also at this point, parts of our brain such as the cerebral cortex are finished growing and will not grow anymore throughout life.
While the rest of our body shrinks as we get older, our noses, earlobes and ear muscles keep getting bigger. That's because they're made mostly of cartilage cells, which divide more as we age.
Answer: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born. When you look at a baby's face, so see mostly iris and little white. As the baby grows, you get to see more and more of the eyeball.
Deep within the hypothalamus, at the base of the brain, a small cluster of around 50,000 nerve cells form the suprachiasmatic nuclei (SCN).
Lungs are the most difficult organ to transplant because they are highly susceptible to infections in the late stages of the donor's life. They can sustain damage during the process of recovering them from the donor or collapse after surgeons begin to ventilate them after transplant.
The liver has a unique capacity among organs to regenerate itself after damage. A liver can regrow to a normal size even after up to 90% of it has been removed.
"The kidneys, on the other hand, are very resilient." Harvested kidneys can remain viable for 24 to 36 hours in cold storage, longer than any of the other top-four transplant organs. Lungs can remain viable for 6 to 8 hours, Lima said, and the liver can remain in cold storage for about 12 hours, according to Dr.
Body organs like ears,nose and tongues do not have bone and instead they have a hard muscular structure called cartilage.
The skin is the body's largest organ.
Humans have five vital organs that are essential for survival: brain, heart, kidneys, liver and lungs.
