Among the many organs in the human body, some are vital to our lives, such as the heart, lungs, liver, etc. However, some organs can be considered "useless" to a certain extent because our bodies can still function normally even if they are removed. Today, let’s discuss these “useless” organs and see how many of them you know.

How many organs are there in the human body?

Generally speaking, scientists believe that there are only five organs in the human body that are necessary for survival, namely the brain, heart, liver, kidney (at least one), and lungs (at least one). While other scientists believe that there are a total of 206 organs in the human body, including every tooth and every bone, some histologists believe that there are a total of 284 organs in the human body because each bone is classified as an independent of organs. In general, organ calculation is a very troublesome and ambiguous thing. Different calculation methods will get different results, so there is no definite answer. Among the many organs in the human body, some are vital to our lives, such as the heart, lungs, liver, etc. However, some organs can be considered 'useless' to a certain extent because our bodies can still function normally even if they are removed.

As the human body ages, its organs are also "shrinking"

When it comes to aging, many people will think of wrinkles, spots, hunched back and other symptoms, but in fact, while the human body is aging, various organs are also tending to "shrink" A research survey conducted by an American university among people aged 45-85 found that. As middle-aged people age, the heart shrinks by an average of 0.3 grams per year. The human brain grows to about 1.4 kilograms in adolescence and gradually shrinks from the age of 20, and will shrink by 10%-15% in a lifetime. Among the many organs in the human body, some are vital to our lives, such as the heart, lungs, liver, etc. However, some organs can be considered 'useless' to a certain extent because our bodies can still function normally even if they are removed.

Which organs will not die if a person is removed? 6 "useless" organs of the body, how many do you know

1. spleen For the human body, the spleen is its largest immune organ and plays an important role. However, the spleen is very fragile and easily damaged. In the event of severe trauma, the spleen may rupture and even become irreparable. In this case, surgical removal of the spleen is the only option to save the patient's life. Although spleen removal will not endanger life, it will have a certain impact on the body's immunity and hematopoietic function. Therefore, after splenectomy surgery, patients need to pay more attention to diet and take exercise, go to bed early and get up early to improve immunity. 2.Appendix The appendix is ​​a long, slender, tube-like organ that connects to the large intestine. In the past, it was thought to have no function, but now research suggests the appendix may play a role in our immune system. If we have to remove the appendix because of illness, the human body can still continue to live a normal life without having a big impact on the body. Among the many organs in the human body, some are vital to our lives, such as the heart, lungs, liver, etc. However, some organs can be considered 'useless' to a certain extent because our bodies can still function normally even if they are removed. Today, let’s discuss these “us - Lujuba 3. Wisdom teeth Wisdom teeth refer to the third molar on the alveolar bone in the human oral cavity. They are exactly the seventh and eighth teeth counting from the incisors. Wisdom teeth erupt relatively late, usually around 16 -Grows out between the ages of 25 and 25. Since people's wisdom also tends to mature at this time, wisdom teeth are regarded as a symbol of "wisdom." Wisdom teeth have actually been regarded as remnants of human evolution. Their original function was to "molar teeth" and act as millstones. is used to grind meat to help the body digest and absorb food better. However, as human diets gradually become more refined, many foods no longer need to be ground, so wisdom teeth gradually deteriorate. 4. Tonsils

Among the many organs in the human body, some are vital to our lives, such as the heart, lungs, liver, etc. However, some organs can be considered 'useless' to a certain extent because our bodies can still function normally even if they are removed. Today, let’s discuss these “us - Lujuba

Tonsils are located in the throat. They were once part of the immune system and helped us fight off infections. However, as we age, our tonsils lose their role and may cause sore throats and infections. Therefore, many doctors recommend removing the tonsils while the child is growing. 5. Gallbladder As an organ that stores bile, the gallbladder is prone to inflammation and stones, which can make people extremely painful. Many people in the world have their gallbladders removed every day.Although it is not life-threatening, what will be the impact after the gallbladder is removed? Digestive function may be affected in the short term after the removal surgery, but over time, the common bile duct can gradually replace the gallbladder's role in daily life Life will basically not be affected. However, in recent years, studies have shown that removing the gallbladder will increase the risk of bowel cancer, but this conclusion is still controversial. 6. tailbone tailbone is a residual part of human evolution. It has no effect on its own, but if there is a disease in the tailbone that affects your life, surgery will be needed to relieve the condition, otherwise it may affect the health of other parts of the body.

Human body organ aging timetable, don’t wait until it breaks down before replenishing it!

1. Skin After the age of 20, the thickness of the skin slowly begins to decrease, and the number of dermal fibroblasts also decreases. After the age of 25, the rate of skin collagen production slows down, dead skin cells will not fall off quickly, the amount of new skin cells generated may be slightly reduced, and the skin begins to age naturally. And as we age, the problem of skin aging becomes more obvious. 2. Lungs Among the many organs in the human body, some are vital to our lives, such as the heart, lungs, liver, etc. However, some organs can be considered 'useless' to a certain extent because our bodies can still function normally even if they are removed. Today, let’s discuss these “us - Lujuba The lungs begin to age at the age of 20. Lung capacity begins to decline slowly from the age of 20, and by the age of 40, some people begin to be breathless. At the age of 30, men inhale 946 milliliters of air with each breath, and by the age of 70, this number drops to 473 milliliters. 3. Bones 35 Around the age of 35, human bone mass reaches its peak, and then the rate of bone fracture will exceed the rate of formation, resulting in a gradual decrease in bone mass in the body. Starting from the age of 40, the rate of bone loss will gradually increase. Men and women will lose 10% and 5% of bone mass respectively every 10 years. 4. The brain starts to age at the age of 20. As we age, the number of nerve cells (neurons) in the brain gradually decreases. The number of nerve cells reaches about 100 billion when we are born, but it starts to decrease year by year from the age of 20. At the age of 40, the number of nerve cells begins to decrease at a rate of 10,000 per day, which affects memory, reasoning ability, thinking speed and the ability to process images in the mind. 5.Heart "Modern Geriatric Cardiovascular Disease" points out that after the age of 45 for men and 55 for women, the heart's pumping and blood transfusion efficiency decreases, and the risk of cardiovascular disease increases. 6. Eyes Among the many organs in the human body, some are vital to our lives, such as the heart, lungs, liver, etc. However, some organs can be considered 'useless' to a certain extent because our bodies can still function normally even if they are removed. Today, let’s discuss these “us - Lujuba Many people start to suffer from presbyopia at the age of 40; by the age of 60, the light received by the retina is only one-third of that at the age of 20. Human beings gradually develop from embryonic stem cells, which can develop into various types of cells. When we are born, these various cell types are replaced by adult stem cells. Adult stem cells have limited differentiation ability and can repair damaged parts of the body, such as healing wounds, renewing epidermis, growing hair, etc., but cannot regenerate. Therefore, as far as current research is concerned, most organs of the human body are unable to achieve regenerative functions. Only a few organs, such as the liver, can regenerate. Conclusion: In summary, there are many parts of the human body that have no substantial role, and they will not have any impact even if they are removed. Therefore, you must have a better grasp of the mysteries of the human body, otherwise you will always fall into misunderstandings, and if you fail to take timely improvement measures when there is a disease in the body, it may cause obvious harm after the disease in these parts.
