The human body is composed of hundreds of trillions of individual cells, and the cell + cell matrix constitutes the four major tissues of the body: epithelial tissue, muscle tissue, neural tissue , connective tissue . Several tissues aggregate together to form organs with certain structure and functions. In medical clinical practice, human organs have 49 major categories: nerves, circulation, digestion, breathing, exercise, immunity, endocrine, excretion, and reproduction.
As medicine's research on organs gradually deepens, many "secrets" of organs have been revealed, such as:
Brain - commander, ischemia, sugar deficiency, and lack of sleep will all have an impact.
Heart - the source of power, long-term overwork, the third high will stop it.
liver - chemical factory, drinking alcohol, drugs, and getting angry will affect liver efficiency.
Lungs - oxygen station, harmful gases and virus invasion will make the lungs worry.
Stomach - Transfer warehouse, cold food, spicy food, and toxic food will induce stomach resistance.
Kidney - Excretion station, holding urine, lack of water, sitting for a long time, saltiness, etc. will damage the kidneys.
Because there are too many organs, people can only remember what is commonly used, and what is not commonly used is "automatically filtered". For some knowledge of organs that are partial, many people really need to "sweep and literate": the largest organ is the skin; body hair is also the organ; a healthy liver can regenerate even if it is cut off two-thirds of it; the eyes cannot be compatible with the body, otherwise it will be "soluble", etc.
Influenced by factors such as natural environment and species competition, human organs have gradually evolved, improved, and adjusted to become what they are now. Even the smallest organs are still channels and bridges to maintain certain functions, which are irreplaceable, and defects will cause "irreversible consequences."
However, in medical clinical practice, some organs are "cleared" from the human body due to diseases, aging and other reasons, which does not have much impact on health and lifespan. Is it true? Let me list a few of the things I often hear and talk about:
, gallbladder
is adjacent to the liver, with a volume of about 30-60 ml, which can store, concentrate, release bile, and secrete some mucus and antibodies. As a cavity organ, the gallbladder has been often associated with negative information such as " gallstone " and " gallbladder polyps " in recent years, and has gradually become a "bad organ". In general, it is easy to become a breeding ground for gallbladder stones and inflammation. If you have any problems, you will sprout polyps and accidentally cause gallbladder cancer.
If the gallbladder is cut off, the bile coming out of the liver will go directly into the intestines by taking a shortcut, causing problems such as indigestion, diarrhea, abdominal distension, and degraded quality of life in the short term. Usually, the body can slowly adapt to it for 3 months of self-adjustment.
Reminder : If the cholecyst is cut off, the common bile duct bordering it will slowly replace the gallbladder, which will have an impact in the short term, but it can slowly adapt in the long term. However, the gallbladder is not an "dispensable" organ. Some studies believe that removing the gallbladder also has the risk of bile duct stones and and the risk of intestinal cancer.
, tonsil
tonsillitis causes fever, which is the experience of many people; tonsil suppuration makes people feel painful; tonsil swollen, which may affect smooth breathing; tonsil stones are one of the sources of oral odor. Some people have repeated tonsil problems and their lives seem to be worn out without passion.
Reminder : Tonsills are not optional, nor can they be removed casually. Tonsils are the human immune organ . It forms the first immune line in the throat and is of great use to children and people with incomplete immune functions.
, appendix
Many people's impression of the appendix is based on memories such as "taking leave for trouble because of the incident", "organs that can cause trouble the most", "organs that are highly inflammatory". The thickness of an adult appendix is like a little finger, with hollow inside, connected to the intestine, and is located in the lower right abdomen of the human body.
Once the appendix has inflammation, it is an acute disease, causing severe abdominal pain. appendicitis is the most common case of surgical acute abdominal disease, and it will be more troublesome to not rescue in time.
Appendicitis usually solves the problem with one-size-fits-all cut, and then the abdominal wound is sutured, and there is no effect after recovery.
Reminder : Appendix removal is a measure to prevent inflammation, but it cannot be regenerated. Studies have shown that there are many probiotics in the empty appendix warehouse, which has a certain impact on the health of intestinal bacterial flora ; the appendix also has a "side business" that produces lymphocytes and , which contributes to immunity. You must maintain the appendix in daily life and do not cut it off if you have nothing to do.
, sinus
0 sinus is hidden in the nasal cavity, with a total of 4 pairs of 8 sinus, namely frontal sinus, ethmoid sinus, maxillary sinus , and sphenoid sinus . If the nasal cavity is a passage, then the sinus is the room next to the passage. In the sinuses and nasal cavity, there is nasal mucosa covered.
Sinus is a cavity tissue. People usually hear it more often, either sinusitis s or sinus polyps. Anyway, I don’t have a good impression. Especially , the upper respiratory tract infection of , often affects the sinus, causing troubles such as unclear vision, otitis media .
Reminder : If the sinus disappears, the "room" next to the nasal cavity will disappear, which can reduce the risk of sinus inflammation, but the intracranial weight of a person will change, the head will become heavy and stuffy, and the walking will be unstable; the area of the nasal mucosa will decrease, and the ability to regulate temperature will become worse; the nose is inexplicably The nosebleed , the chance of mucus increases, etc.
5, wisdom teeth
There are 4 wisdom teeth, which are located at the third molar. In the past, the food was vulgar, and wisdom teeth played a major role in grinding food. However, with the evolution of civilization, the food became thinner and softer, and wisdom teeth slowly completed the historical mission and simply hid in the alveolar and did not grow.
However, some wisdom teeth "have not sleepy" and "epied" at any time, which caused trouble to the parties involved, either swelling, pain or ugly, and it also affected a lot of time.
Reminder : If wisdom teeth are wormed, blocked, or inflamed, they can only be removed. But if nothing happens, don’t move your wisdom teeth easily, because it may cause the problem of cheek collapse. It can also be used as a substitute for "missing teeth", which is much better than dentures .
6, tailbone
tailbone, also known as tailbone, is at the top of the buttock groove and can be reached by hand. I can't remember it at all, but as long as I fall on my back, sit down and bump, the tailbone will definitely be severely painful and broken to protest, which is more troublesome.
Reminder : The tailbone is not optional. Its existence can help the body balance and load-bearing; it can reduce spinal pressure; the discomfort after nasal blockage can be relieved.
Here are just a few examples, and there are many organs that we don’t know, which are actually working or ready to work, and cannot be regenerated. Once cut off, they will not grow out. All organs in the human body are useful, and it is reasonable to exist. Unless there is indeed a lesion or a chain is lost, no one can be left behind.
