And topping it all off is the brain. It is the bossiest part of your body; it controls virtually every other part.
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.
Your heart is an incredibly hardworking organ. In five minutes, it will pump five litres of blood around your body. After an hour, it will have pumped 300 litres in 4,200 heartbeats.
The liver is the largest solid organ in mammals, and it also performs many functions in the body, which is considered to be the busiest organ in the body.
Vital Organs
The human body contains five organs that are considered vital for survival. They are the heart, brain, kidneys, liver, and lungs. The locations of these five organs and several other internal organs are shown in Figure 10.4. 2.
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.
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 following are the six heaviest organs found in the body of a human being: The first heaviest organ is the skin with a mass of four to five kg. The liver is the second heaviest organ in the body, which discharges bile.
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.
Tooth enamel is the hardest part of the body. The toughest and most mineralized component in the human body is dental enamel. It's not a bone, but a tissue. This tissue has a significant mineral content, making it the hardest substance available.
The strongest part of the body is the skeleton, as bones in general are ounce for ounce stronger than steel. More specifically, the strongest bone in the human body is the femur, as it takes approximately 4,000 newtons of force to break, on average.
The heart is the most powerful source of electromagnetic energy in the human body, producing the largest rhythmic electromagnetic field of any of the body's organs. The heart's electrical field is about 60 times greater in amplitude than the electrical activity generated by the brain.
The human brain can generate about 23 watts of power (enough to power a lightbulb).
The brain is complex; in humans it consists of about 100 billion neurons, making on the order of 100 trillion connections. It is often compared with another complex system that has enormous problem-solving power: the digital computer.
The appendix may be the most commonly known useless organ.
Many years ago, the appendix may have helped people digest plants that were rich in cellulose, Gizmodo reported. While plant-eating vertebrates still rely on their appendix to help process plants, the organ is not part of the human digestive system.
Muscle, tendons, ligaments, fat, fibrous tissue, lymph and blood vessels, fasciae, and synovial membranes are all examples of soft tissue that connects, surrounds or supports internal organs and bones. Fats are widely regarded as the softest tissues.
The brain is certainly the least understood organ in the human body. If you ask a cardiologist how the heart works, she will give an engineering description of a pump based on muscle contraction and valves between chambers. If you ask a neurologist how the brain works, how thinking takes place, well . . .
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.
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.
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 intestines are our most beautiful organs”, Kraneveld concludes. “The nervous system in the intestines is unimaginably complex, and is comparable to our brain.
Kidney is the organ responsible for purification of blood. The major excretory product in humans is urea. Urea, excess water and other waste products are filtered from the blood by kidneys. Kidneys produce urine which has all these wastes and is thrown out while urination.
