There is no other part of the body that knows no rest beside the heart. The few moments after the heart stops beating the body dies. The condition of sudden stopping of heartbeat called cardiac arrest, and leads to death if the heart activity isn't restored within a few minutes.
Researchers at Vanderbilt University in Nashville, Tennessee, have found that while you are asleep, the only body part that remains active is the ear.
Brains can work 24 hours a day with no rest.
Explanation: The growth of most structures(muscles, bones etc...) of human body stops after adolescence. But here is one special structure called cartilage that continue to grow till death.
Stomach. The stomach performs four main functions: mechanical digestion by contracting to smash up food, chemical digestion by releasing acid to help chemically break up food, and then absorption and secretion. The stomach is sometimes surgically removed as a result of cancer or trauma.
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.
What happens when someone dies? In time, the heart stops and they stop breathing. Within a few minutes, their brain stops functioning entirely and their skin starts to cool. At this point, they have died.
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 .
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.
1-3am is the time of the Liver and a time when the body should be alseep. During this time, toxins are released from the body and fresh new blood is made. If you find yourself waking during this time, you could have too much yang energy or problems with your liver or detoxification pathways.
Primary Meridian: Liver
If you're waking up in the middle of the night after a cocktail or two, it's because your liver is working in overdrive to relieve your body of excess toxins. The liver cleanses our blood and when this process gets interrupted, it can result in low energy and feelings of angst the following day.
If you wake up between 1 am and 3 am it means your liver was overloaded. The liver is responsible for detoxifying our bodies and processing emotions each night. You may be suffering from an unhealthy diet, excess alcohol consumption, and/or unresolved anger or high levels of stress.
Your heart is an incredibly powerful organ. It works constantly without ever pausing to rest. It is made of cardiac muscle, which only exists in the heart. Unlike other types of muscle, cardiac muscle never gets tired.
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.
Although some patients who have a diseased portion of their liver removed are unable to regrow the tissue and end up needing a transplant. Researchers from Michigan State University believe blood clotting factor fibrinogen may be responsible.
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.
One of the wildest innovations is “living funerals.” You can attend a dry run of your own funeral, complete with casket, mourners, funeral procession, etc. You can witness the lavish proceedings without having an “out-of-body” experience, just an “out-of-disposable-income” experience.
Hearing is widely thought to be the last sense to go in the dying process. Now, the first study to investigate hearing in palliative care patients who are close to death provides evidence that some may still be able to hear while in an unresponsive state.
Visual or auditory hallucinations are often part of the dying experience. The appearance of family members or loved ones who have died is common. These visions are considered normal. The dying may turn their focus to “another world” and talk to people or see things that others do not see.
Anatomy & Function
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.
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.
