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 .
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 holdouts? Your arteries, skin, liver, lungs, and digestive tract, and certain parts of your brain. They're all continually refreshed—if you're healthy. "It's called maintenance regeneration.
The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.
The body's ability to heal itself naturally is actually not a new thing. A fractured bone will regrow and heal the break. Cut yourself shaving, and the skin will heal. There are many examples of our body's innate ability to heal injuries.
Stress may cause you to not get enough sleep, eat poorly, and smoke or drink more, which can interfere with healing. Medicines such as corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), and some chemotherapy drugs can slow healing. Smoking can delay healing after surgery.
The eyes, in conjunction with other bodily functions, work hard to keep vision clear and rely heavily on natural regeneration to self-repair and heal when necessary. This is especially true for the cornea since it stands on the front line and can endure wounds, scars, erosion problems and other issues.
Of all the organs in the human body, the heart is without a doubt the hardest worker. Beating an average of 72 times per minute, it's responsible for pumping 2,000 gallons or more of blood through the body each day.
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.

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.
As you can see, it's important to understand the five reasons why a wound won't heal: poor circulation, infection, edema, insufficient nutrition, and repetitive trauma to the wound.
Depending on the type of injury that has occurred, the brain will likely be the organ responsible for beginning the healing process. To do this, signals are relayed throughout the nervous system: brain, spinal cord and nerves.
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.
Answer: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born.
Muscles and tendons generally heal the fastest. These parts of the body recover more quickly thanks to an ample blood supply. The circulatory system provides muscles with plenty of nutrients and oxygen needed for healing.
The largest solid internal organ is your liver. It weighs approximately 3–3.5 pounds or 1.36–1.59 kilograms and is about the size of a football.
Answer and Explanation: The heaviest organ is the skin. This makes sense as the skin is also the largest organ of the human body. With an average weight of about 4.5kg or nearly 10lbs, the skin is much heavier than the second heaviest organ, the liver.
Your Liver: Your Coolest Organ.
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.
Skin: The skin is our body's most sensitive organ. The skin is the largest organ of the body, made up of water, nutrients, lipids, and mineral deposits.
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.
Turns Out, Mammals Have Those Genes Too. Damage to the retina is the leading cause of blindness in humans, affecting millions of people around the world. Unfortunately, the retina is one of the few tissues we humans can't grow back.
Unfortunately, eyesight cannot be improved naturally and there is no way to change a refractive error, such as myopia, hyperopia, astigmatism, or presbyopia. These types of visual conditions can be treated with glasses, contact lenses, or refractive surgery.
Your eyes can roll back into your head for several reasons. The most common causes include seizures, fainting spells, or an eye condition called nystagmus. Many times, your eyes rolling back and other accompanying symptoms is due to an underlying health condition.
