The lungs are generally considered the third-largest organ in the human body by weight, following the skin (largest) and the liver (second largest), crucial for gas exchange, though some rankings might place the brain or intestines higher depending on criteria (weight vs. surface area). Together, the lungs weigh about 2.2 pounds (1 kg) and provide a massive surface area for oxygen absorption and carbon dioxide release.
The Liver is the second largest organ in the human body. It functions both as a gland and an organ. It performs more than 500 functions, such as detoxification, protein and vitamin absorption, and the production of chemicals that help digest food and helps some of the other organs in performing their functions.
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.
The liver holds the largest amount of blood at any given time. The liver is highly vascular and receives about 25% of the cardiac output, making it a significant blood reservoir in the body.
But that doesn't, and shouldn't necessarily, stop people. The most poisonous part of your body is probably your liver - more specifically, the fat-soluble vitamin A that is stored there.
As well as the obvious 'dead' cells such as your hair and nails, there is one area of living cells that doesn't use a direct blood supply. The only living cells in the body that aren't directly served by blood vessels are those of the cornea in the eye.

Yes, you can live without a spleen (a splenectomy), and many people live long, healthy lives, but you have a lifelong increased risk of severe, rapidly progressing bacterial infections because the spleen helps fight germs and filter blood. Other organs, like the liver, take over many of its functions, but lifelong precautions are crucial, including staying current on vaccines (like pneumococcal and meningococcal), getting annual flu shots, and potentially taking daily antibiotics, plus seeking immediate medical care for fever or signs of infection.
The heart is the busiest organ of the human body.
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.
Here are some of the worst offenders when it comes to liver health:
The heaviest organ is the skin, which is about 16% of body weight. Organ weight measurements often come from autopsies of healthy organs.
The ten largest organs in the body are – skin, liver, brain, lungs, heart, kidney, spleen, pancreas, thyroid and joints.
The 12 organ systems are the integumentary system, the skeletal system, the muscular system, the lymphatic system, the respiratory system, the digestive system, the nervous system, the endocrine system, the cardiovascular system, the urinary system, and the female and male reproductive systems.
Your skin, along with your hair, nails, oil glands and sweat glands, is part of the integumentary (in-TEG-you-MEINT-a-ree) system. “Integumentary” means a body's outer covering.
Some people are born without a spleen or need to have it removed because of disease or injury. The spleen is a fist-sized organ found in the upper left side of your abdomen, next to your stomach and behind your left ribs. It's an important part of your immune system but you can survive without it.
Avoiding raw and undercooked eggs is recommended if you don't have a spleen. Raw and undercooked eggs are at high risk for Salmonella, which can cause food poisoning. If you don't have a spleen, this can make you very sick. Always cook eggs until the yolk and white are firm.
If part of the spleen is removed, the spleen may regenerate. If a patient undergoes a total splenectomy (removal of the entire spleen), it will not regenerate, but many functions of the spleen are taken over by other organs. However, absence of a functioning spleen increases the risk of bacterial infection.
The Queen's organ was designed to replace the Johann Snetzler organ in the Henry VII Chapel (the Lady Chapel) at Westminster Abbey. The instrument is a gift from the Lord Mayor and the Corporation of London to Her Majesty, Queen Elizabeth II in celebration of her Diamond Jubilee.
The brain is the most complex part of the human body. This three-pound organ is the seat of intelligence, interpreter of the senses, initiator of body movement, and controller of behavior. Lying in its bony shell and washed by protective fluid, the brain is the source of all the qualities that define our humanity.
Skin is the largest organ of our body. The skin is made up of three main layers: the epidermis, dermis and subcutis.
Detailed Solution. The correct answer is Brain. Brain organs will not feel any pain on being pricked by a needle. The brain is a painless organ.
Golden blood is the rarest kind of blood known in the world. It's also called Rh null blood, and about 43 people have ever been reported to have it. "The name 'golden blood' can sound like this is blood that's somehow more pure or safe for transfusions,” Dr. Otrock shares.
The Epidermis. The epidermis is composed of keratinized, stratified squamous epithelium. It is made of four or five layers of epithelial cells, depending on its location in the body. It does not have any blood vessels within it (i.e., it is avascular).
