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.
Only five organs — the brain, heart, liver, at least one kidney, and at least one lung are absolutely essential for living. Losing total function of any one of these vital organs spells 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.
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.
The liver is the only organ in the body that can grow cells and regenerate itself.
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.
For example, thoracic organs like the heart and lungs, can only remain viable for transplant after being outside of the body for four to six hours, while the liver can function for up to 12 hours and kidneys up to 36 hours.
In such cases, return can be coordinated with the funeral director who took care of the funeral arrangements in the case. Organs are retained only when necessary to facilitate proper examination. In most cases, no whole organs are retained.
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.
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.
Liver is the most nutrient dense organ meat, and it is a powerful source of vitamin A. Vitamin A is beneficial for eye health and for reducing diseases that cause inflammation, including everything from Alzheimer's disease to arthritis.
The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature.
Your Liver: Your Coolest Organ.
But here is one special structure called cartilage that continue to grow till death. Also one important point to mention is that cartilage is present at several sites in our body but mainly the cartilage(softer connective tissues) of ear and nose continue to grow.
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.
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.
For most people, the normal number of times to urinate per day is between 6 – 7 in a 24 hour period. Between 4 and 10 times a day can also be normal if that person is healthy and happy with the number of times they visit the toilet.
The Effects of Alcohol on One Kidney
But, if you have only one kidney, you must live a healthy lifestyle. So, if you have one kidney and drink alcohol, you can cause life-threatening issues. A healthy lifestyle includes a nutritious diet, exercise, and regular check-ups. This means no alcohol.
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).
