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.
The largest fraction of energy goes to the liver and spleen, with the brain coming next. About 75% of the calories burned in a day go into these basic functions. A full 25% of all basal metabolic energy consumed by the body is used to maintain electrical potentials in all living cells.
May is the Month of the Brain, our most energy-consuming organs. Representing only 2% of the weight of an adult, the brain consumes 20% of the energy produced by the body.
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.
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.
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.
Your nervous system is the master communication network for innate intelligence. The brain and spinal cord, also known as the Central Nervous System (CNS), control all functions of the body by a process that sends signals from the brain out via the nerves and then out to the body.
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.
Most of the body's energy reserves—about 80-85% in a healthy adult are in stored fats. While it may seem like the fat that pads our bodies sits there, stubbornly refusing to budge, fat is a very active tissue that is constantly turning over its inventory. After a meal, fat is put into storage.
Remarkably, the brain alone consumes 20% of the body's chemical energy, even though it accounts for only 2% of the body's mass.
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.
Fat is the body's most concentrated source of energy, providing more than twice as much potential energy as carbohydrate or protein (9 calories per gram versus 4 calories each per gram). During exercise, stored fat in the body (in the form of triglycerides in adipose or fat tissue) is broken down into fatty acids.
The liver is the only organ in the human body that is capable of exporting nutrients for energy production to other tissues. Therefore, when a person is in between meals (fasted state) the liver exports nutrients and when a person has just eaten (fed state) the liver stores nutrients within itself.

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.
Weighing in at roughly 2 percent of a person's body weight, the liver is an extremely high-functioning, adaptable organ. But even more amazing is its ability to regenerate. When a portion of the liver is removed, the liver's cells divide and regrow the lost tissue within days.
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.
3 am to 5 am: The lungs are active. You may feel sadness or have shallow breathing if your lungs are out of balance. Practice activating the vagus nerve before bed with breathing exercises, and take some time to process your emotions with a trusted friend. 5 am to 7 am: The large intestine is active.
5am - 7am. LARGE INTESTINE | Wake up, release bowels, meditate.
Recently the British Medical Journal published the findings of two scientists from the University of New South Wales in Australia. Their study showed that we breathe away more than 80 percent of our fat via our lungs.
Weight is controlled in the hypothalamus, a small area at the base of the brain, located in the midline, behind the eyes. Within the hypothalamus are nerve cells that, when activated, produce the sensation of hunger. Red: the hypothalamus.
The hypothalamus region of the brain is essential for metabolic control and the area known as the ventromedial hypothalamus is known to regulate body weight, eating, and glucose balance.
Answer and Explanation: The liver, brain, and heart consume the most oxygen in the body. The liver consumes 20.4%, the brain 18.4%, and the heart 11.6%.
