The heart pumps blood containing oxygen to every part of your body. At the same time, it pumps the blood without oxygen back through the lungs where it picks up new oxygen, This cycle is repeated every time your heart beats, 24 hours a day, everyday.
Brains are a part of human beings, which controls all the functions of the body. Our brain needs rest every day, without which body functions will be hampered.
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).
Heart is the muscular organ which works continuously as a pump for the transport of blood. It's one of the most vital organs in the human body.
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.
Decompensation progresses over a period of minutes even after the pulse is lost. Even when vascular collapse is the primary event, brain and lung functions stops next. The heart is the last organ to fail.
Heart. The heart is the most important organ of the circulatory system, which helps deliver blood to the body. It works with the lungs to add oxygen to blood and pump this freshly oxygenated blood through the blood vessels and around the body.
Transplanted Organs Don't Last Forever
Meanwhile, a liver will function for five years or more in 75 percent of recipients. After a heart transplant, the median survival rate of the organ is 12.5 years. A transplanted pancreas keeps working for around 11 years when combined with a kidney transplant.
The heart is the busiest organ of the human body.
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.
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.
Answer: The eyeball is the only organism which does not grow from birth. It is fully grown when you are born. When you look at a baby's face, so see mostly iris and little white. As the baby grows, you get to see more and more of the eyeball.
Summary: Skin and liver cells appear to have their own circadian clock. Both the liver and skin respond to changes in light and maintain critical function, independent of the brain's circadian rhythm.
1-3am is the time of the Liver and a time when the body should be alseep. During this time, toxins are released from the body and fresh new blood is made. If you find yourself waking during this time, you could have too much yang energy or problems with your liver or detoxification pathways.
5am - 7am. LARGE INTESTINE | Wake up, release bowels, meditate.
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.
Busiest Organ of the Body:
The liver is an organ that works to detoxify the blood. Kidneys and bladder are organs that eliminate waste from the body in the form of urine.

Lungs are the most difficult organ to transplant because they are highly susceptible to infections in the late stages of the donor's life. They can sustain damage during the process of recovering them from the donor or collapse after surgeons begin to ventilate them after transplant.
“Where extracorporeal machines or transplantation can support or replace the function of organs such as the heart, lung, liver or kidney, the brain is the only organ that cannot be supported or replaced by medical technology.”
Aside from the likes of hair and nails – which can continue growing for a short time after death – there are really only two external body parts that grow in size for the rest of your life. These are your ears and your nose.
Because the brain is so rich in nerve cells, or neurons, it is the most energy-demanding organ, using one-half of all the sugar energy in the body. Brain functions such as thinking, memory, and learning are closely linked to glucose levels and how efficiently the brain uses this fuel source.
It is well established that the brain uses more energy than any other human organ, accounting for up to 20 percent of the body's total haul. Until now, most scientists believed that it used the bulk of that energy to fuel electrical impulses that neurons employ to communicate with one another.
