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.
Humans have five vital organs that are essential for survival: brain, heart, kidneys, liver and lungs.
Organs that can be transplanted are the heart, kidneys, liver, lungs, pancreas and intestines. The skin, bone tissue (including tendons and cartilage), eye tissue, heart valves and blood vessels are transplantable forms of tissue.
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.
Teeth are the ONLY body part that cannot repair themselves. Repairing means either regrowing what was lost or replacing it with scar tissue. Our teeth cannot do that. Our brain for example will not regrow damaged brain cells but can repair an area by laying down other scar-type tissue .
The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.
The human brain is the most resilient organ in the body.
Although some patients who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant.
If you have both kidneys completely removed, you will not make any urine. You will need to have kidney dialysis. This is a way of getting rid of waste products and excess water that the kidneys normally filter out of your blood. Dialysis means you can lead a more or less normal life without a working kidney.
While your heart is a vital organ, the brain (and the nervous system that attaches to the brain) make up the most critical organ system in the human body. The human nervous system is responsible for coordinating every movement and action your body makes.
The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.
Answer and Explanation: The mouth is the fastest healing organ, according to Brand et al. (2014). This is due to the presence of saliva, that moisturizes the wound, improves immune response to wound healing, and contains other wound-healing promoting factors.
Answer: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born.
Vestigial organs are parts of the body that once had a function but are now more-or-less useless. Probably the most famous example is … the appendix, though it is now an open question whether the appendix is really vestigial.
Research suggests that even as your body transitions into unconsciousness, it's possible that you'll still be able to feel comforting touches from your loved ones and hear them speaking. Touch and hearing are the last senses to go when we die.
This usually begins in the liver, which is rich in enzymes, and in the brain, which has high water content. Eventually, though, all other tissues and organs begin to break down in this way.
It is natural to wonder what happens when you die. From a physical standpoint, death occurs when the body's vital functions stop entirely, including respiration (breathing), heart function, and, finally, brain function.
