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.
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.
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 . . .
Answer and Explanation:
Our heart works tirelessly 24/7 until we die to make sure we have blood pumping.
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. The weight of the liver is about 1.5 kg. The brain is the third heaviest organ with an approximate mass of 1.5 kg.
The pineal gland is the smallest organ in the human body. The pineal gland is located near the center of the brain. The name pineal comes as pineal is a small pine-shaped gland.
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.
Your heart pumps out about 70 milliliters (two ounces) of blood every time it beats. And it does this over three billion times in the average person's lifetime.
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 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.
New Human 'Organ' Was Hiding in Plain Sight. The interstitium, scientists found, is under our skin and between our organs. Understanding it may eventually help treat disease.
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.
Teeth are the ONLY body part that cannot repair themselves. Repairing means either regrowing what was lost or replacing it with scar tissue. Our teeth cannot do that. Our brain for example will not regrow damaged brain cells but can repair an area by laying down other scar-type tissue .
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.
The liver is the only organ in the human body that can grow cells and regenerate. A donated liver from someone who has died (a deceased donor) can further be split into two pieces and transplanted into two different people to save their lives.
“The intestines are our most beautiful organs”, Kraneveld concludes. “The nervous system in the intestines is unimaginably complex, and is comparable to our brain.
The brain is the only organ in the human body that cannot be transplanted. The brain cannot be transplanted because the brain's nerve tissue does not heal after transplantation.
Kidneys: Kidneys are the most needed and most commonly transplanted organ. Kidneys are responsible for filtering waste and excess water from the blood and balancing the body's fluids.
Kidney transplantation surgery is relatively noninvasive with the organ being placed on the inguinal fossa without the need to breech the peritoneal cavity. If all goes smoothly, the kidney recipient can expect to be discharged from the hospital in excellent condition after five days.
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 levels of biological organization shown in Figure 1, from largest to smallest, are organism, organ system, organ, tissue, and cell. This means that many cells make up a tissue, several tissues make up an organ, different organs work together in an organ system, and an organism contains more than one organ system.
The skin is the body's largest organ.
