It's like in the office.
Someone is always fishing.
This large, delicate tissue of the human body also has some organs that don't seem to be working
So.
Why not just take them out? First of all.
We need to find out who these organs areAppendiceAs everyone knows.
The appendix is used to ask for leave
in the lower right abdomen of the human body.
At the end of the cecum there is a small tube called the appendix, which Darwin thought.
Human ancestors were heavily vegetarian, but later dietary changes led to the degeneration of the cecum into an appendix.
After losing his job, the appendix began to be awkward due to the narrow lumen of the appendix.
It is easy to get clogged and cause inflammation.
It can even cause perforation of the appendix to be life-threatening, therefore.
Some people often have no inflammation of the appendix.
He also chose to cut to eternal ruleBut cut off the appendix early.
Does it really hurt to do so? In fact.
The appendix wall is rich in lymphoid tissue.
Able to produce and deliver immune cells.
Helps the body fight off germs
Meantime. The appendix can also store some probiotics to maintain the microflora environment in the intestines.
It's not for nothing.
Unless the appendix is already in place, direct removal is not recommendedTonsilsTonsils are a nightmare for all elementary school students.
Due to incomplete physical development and low resistance, many children will be poisoned by tonsillitis
The tonsils are located in the throat of a person.
The so-called inflamed palate tonsils, some children are born with hypertrophied tonsils.
It is easy to cause inflammation.
Causes dry itching in the pharynx and difficulty swallowing.
Cough or even fever.
It can even lead to acute nephritis and myocarditis.
In this case, the tonsils should be removed immediately.
But there is one thing to say.
The tonsils also used to protect us when we were young.
It is above the lymphocytes.
It can resist bacteria passing through the pharynx and prevent them from entering the body.
After removing the tonsils.
Acute and chronic pharyngitis can also take advantage of the weakness before the age of 7 years.
The tonsils should not be removed as much as possible.
NipplesThe boy's Mimi is divided into positive and negative sides.
It's really useless
The sixth week in the mother's body.
The boy's breasts were already developing vigorously at this time.
Sex-determining genes are starting to exert their strength.
Androgens stop the breasts from developing, so the boy's boomy is put on pause
Not only is a boy's nipple unable to breastfeed, but it can also be sad, sad, and have nipple syndrome.
It means that some people will have a feeling of lovelessness after being touched on their nipples, and boys will also get breast cancer.
Although the probability is very low.
But it was also enough to make macho men cry.
Maybe the only role of the boy Mimi.
It's just for doing things that are indescribable
SinusesThere are four pairs of cavities on each side of the human nasal cavity.
The sinuses are the frontal sinuses, maxillary sinuses, sphenoid sinuses, ethmoid sinuses and upper respiratory tract infections.
May cause sinusitis.
Causes otitis media and decreased visionSo what happens without sinuses
First of all. Your nose may spew blood, and the nasal mucosa that covers the sinus cavity acts like a humidifier to regulate the temperature and humidity of the air you breathe in your nose
Secondly. Your head will become heavy and more prone to drowning because the sinuses reduce the weight of your head.
Make head movements more flexible to keep your body balanced while increasing the buoyancy of your head in the water.
At last. In a fight you may injure the air in the sinus cavity more heavily.
It can cushion the impact of external forces.
It is more important to protect the eye sockets and brain.
The sinuses resonate with the sound, making it more pleasantCoccyxFossil studies have shown that.
Apes evolved their tails as early as 20 million years ago.
Since apes on land are upright walking.
In the trees, it is moved by the arms, so the tail has become a useless burden, which increases physical exertion and is not conducive to fighting, so in the long evolution.
The tail gradually recedes into the coccyx, which seems to be useless, but the coccyx protects the spine.
The coccyx has a cushion with the base of the spine.
Protect the spine from direct contact with external forces, if there is no impact force after a fall on the coccyx, it will be transmitted directly to the brain, causing damage to the brain, and it has gone through tens of thousands of iterations.
There are still many organs in the human body that are complained about and useless, but just like people who touch fish, they can also work.
These useless organs also protect the human body in a unique way.
