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. But the liver isn't invincible. Many diseases and exposures can harm it beyond the point of repair.
Some tissues such as skin, the vas deferens, and large organs including the liver can regrow quite readily, while others have been thought to have little or no capacity for regeneration following an injury. Numerous tissues and organs have been induced to regenerate.
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.
The only part of the body that cannot repair itself is the tooth. The tooth cannot replace or repair itself in humans. Human teeth don't have the cells necessary to repair damages like other organs and structures do.
The liver is the only organ in the body that can grow cells and regenerate itself. It can actually be split in half and transplanted into two different recipients. A living personal also can have a portion of his or her liver removed, and the portion that remains will regenerate itself to nearly its original size.
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.

Lungs are the most difficult organ to transplant because they are highly susceptible to infections in the late stages of the donor's life.
Generally, the lung is the first organ to fail after injury (failure after 3.7 +/- 2.8 days).
The five vital organs in the human body are the brain, the heart, the lungs, the kidneys, and the liver.
Nerves typically take the longest, healing after 3-4 months. Cartilage takes about 12 weeks to heal. Ligaments take about 10-12 weeks to heal. Bones take about 6-8 weeks to heal on average.
It's true – wounds in the mouth really do heal much faster than cuts to the skin. A study has discovered that the lining of the mouth is permanently primed for healing. The finding could lead to new ways to improve wound-healing elsewhere in the body.
Organs are usually transplanted because the recipient's original organs are damaged and cannot function. The brain is the only organ in the human body that cannot be transplanted. The brain cannot be transplanted because the brain's nerve tissue does not heal after transplantation.
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.
Some common symptoms of many types of organ failure include: Weakness, faintness or fatigue. Drowsiness or loss of consciousness. Difficulty concentrating, confusion.
Heart is the only organ in the body which never rest throughout the entire life. The heart is a hollow muscle that pumps blood throughout the blood vessels by repeated, rhythmic contractions.
The brain is one of the busiest (second only to the liver) and the laziest organs in our entire body. Our brains tend to focus on things which make it feel good, keeping us in our comfort zone.
The most poisonous part of your body is probably your liver - more specifically, the fat-soluble vitamin A that is stored there. Your liver stores it in a safe form, and releases it and its breakdown products in a controlled manner for use by your body.
Transplanted Organs Don't Last Forever
Meanwhile, a liver will function for five years or more in 75 percent of recipients. After a heart transplant, the median survival rate of the organ is 12.5 years. A transplanted pancreas keeps working for around 11 years when combined with a kidney transplant.
A new organ has been discovered hiding in plain sight inside the human body. Known as the mesentery, it was previously thought to be just a few fragmented structures in the digestive system. But scientists have realised it is in fact one, continuous organ.
According to the widely used, although somewhat hard-to-find-credit-for figures, a heart is worth around $1 million in the US. Livers come in second, worth about $557,000 and kidneys cost about $262,000 each. Not to speak about human skin ($10/inch), stomach ($500), and eyeballs ($1,500 each).
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. At the same time, connective tissue begins to weaken.
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.
The heart pumps blood containing oxygen to every part of your body. At the same time, it pumps the blood without oxygen back through the lungs where it picks up new oxygen, This cycle is repeated every time your heart beats, 24 hours a day, everyday. Lungs.
