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 brain is certainly the least understood organ in the human body.
Answer: The internal organs which we cannot see, are the heart, the lungs, the stomach, the liver with the gall-bladder, the pancreas, the spleen, the kidneys and the small and large intestines (bowels).
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.
The pineal gland is the smallest organ in the body that helps in regulating the female reproductive fertility cycles.
We must remember that the most delicate organ in the human body is the brain. Brain is one of the largest and most complex organs of the human body and is made up of more than 100 billion nerves. Brain controls speech, thought, memory, movement and helps in the functioning of many organs in the human body.
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 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.
Kidneys. Most people have two kidneys, but you can survive with just one – or even none (with the aid of dialysis).
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.
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.
Your Liver: Your Coolest Organ.
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 researchers used light touch, pressure, and vibration to assess how sensitive these body parts were in 30 healthy women between the ages of 18 and 35 years. With regard to pressure, the clitoris and nipple were the most sensitive, and the lateral breast and abdomen were the least sensitive.
By weight, the uterus is the strongest muscle in your body. Yes, the jaw is often listed as the winner of the strongest muscle category, but hear us out: the uterus is made up of vertical and horizontal muscle fibres that intertwine to create a mighty muscle force that can birth a baby.
The ears and nose do not have bones inside them. Their inner supports are cartilage or 'gristle', which is lighter and more flexible than bone. This is why the nose and ears can be bent.
Answer: The eyeball is the only organism which does not grow from birth.
