Kidneys. Most people have two kidneys, but you can survive with just one – or even none (with the aid of dialysis). The role of the kidneys is to filter the blood to maintain water and electrolyte balance, as well as the acid-base balance.
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.
For example, people can live relatively normal lives with just half a brain). Other organs can be removed in their entirety without having too much impact on your life.
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: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born.
The brain is certainly the least understood organ in the human body.
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.
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. It is found in all animals with a circulatory system (including all vertebrates).
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.

Most people can live without a stomach or large intestine, but it is harder to live without a small intestine. When all or most of the small intestine has to be removed or stops working, nutrients must be put directly into the blood stream (intravenous or IV) in liquid form.
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.
For most people born with one kidney, we do not know why it happens. In a small number of people, being born with one kidney is part of a syndrome. A syndrome means that the child is born with more than one health problem. In the past, many parents did not even know their child had only one kidney.
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).
The Stapedius, the smallest skeletal muscle in the human body, which is about 1 mm in length, is regarded to be the weakest muscle.
The liver is known as a silent organ, as even when a liver failure occurs, the symptoms often go unnoticed.
The brain has no nociceptors – the nerves that detect damage or threat of damage to our body and signal this to the spinal cord and brain.
The bones of the body do not burn in fire. Why do the bones not burn in fire? For the burning of bone, a very high temperature of 1292 degrees Fahrenheit is required. At this temperature also, the calcium phosphate from which the bones are made will not entirely turn into ash.
The strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars.
Human embryos develop a tail between five and eight weeks after conception. The tail vanishes by the time humans are born, and the remaining vertebrae merge to form the coccyx, or tailbone.
