My old fans should have stocked up
A lot of "physiological knowledge"
(After all, I used to give you popular science before)
Don't you think you don't have much knowledge?
Can you surprise everyone?
Then you're underestimating me
I'll sort it out for you again
7 Physiological Knowledge
One is more outrageous than the other
Let's take a look
①
Knowing you're shocked
I certainly haven't seen it
Because this situation is rare
The incidence is about 1 in 5 million
There is a professional term in medicine
Called: "Repeat the penis"
The reason why there are two
It is because during embryonic development
Accidentally went wrong
Germ cells are formed twice
Genital malformations appeared
Thus a person has two tintins
Some people are lucky
It's not just an extra one
It can also have a complete urethral structure
It is possible to urinate in turns or at the same time
But most of the deformed people
It's all miserable
The second root is dysplasia
It doesn't come in handy at all
It can even be accompanied by ejaculation disorders and infertility
It even affects the functions of the bladder, kidneys and other aspects
②
Similar to the male double butto
It is also the period of embryonic development that is abnormal
A type of congenital malformation that arises
However, compared to the deformity of men
In women, there is usually nothing wrong with this double uterine malformation
As long as puberty is developing normally
It will not affect fertility
In addition, menstruation is influenced by endocrine receptors
The double uterus also does not disrupt endocrine
Therefore, it is normal for girls with double uterus to menstruate
Some people are even seeing gynecological diseases
Or when you're pregnant
Only then will you know that you have a double uterus through the examination
③
Many people have heard of kidney transplants
But few people know about it
A kidney transplant is not about removing a bad kidney and replacing it with a good one
Instead, the original diseased kidney is retained
Find another place and add a kidney
So there will be three kidneys in the body
That's why
It's because the original kidneys are failing
However, it still retains some endocrine function
If the diseased kidney is to be removed
An incision of about 15 cm in size is opened
and remove the 12th rib above the waist
in order to remove the diseased kidney layer by layer
This practice can cause more damage to the body
It's better to keep it without going under the knife
④
This is a very natural physiological phenomenon
It's called "gene chimera."
When your mom is pregnant
There is not only one fertilized egg in the body
Rather, there are two or more of them
But when you're growing and developing
Fuse other fertilized eggs into itself
Absorbed the nutrients of compatriots
So wait until you are born
There are two sets of genes in the body
If you're chimeric with germ cells
Then you have the possibility of inheriting that
The DNA of your dad's siblings
Look for the "birthmark" on your body
If there are that kind of larger pieces
It could be that you absorb other fertilized eggs
Let it become a "birthmark" on your body
⑤
It's actually a technology
And it's very bullish
It's called "delayed interval delivery of multiple births."
Because under normal circumstances
Multiple births are born together
Usually only one to a few minutes apart
However, some people conceive multiple babies at different stages
One of the babies is not yet mature
Premature birth is prone to accidents
Therefore, as far as the physical condition allows
Doctors will consider using this technique
Of course, a very important thing to have a baby is
There are no contractions
I still can't give birth smoothly
So, doctors can take advantage of this
After the pregnant mother gave birth to her first child
Artificially suspend contractions
Let the second fetus not be born for a while
⑥
"Blood type" refers to the type of antigen on the surface of the blood components
But it's not fixed
There are some special unexpected circumstances
Will make you unknowingly "change blood type"
For example: accidentally cut a wound
Leave it alone for a long time
Causes bacterial infections
Chemicals released by bacteria
Causes the antigen to be transiently altered
Your blood type will be changed briefly
This condition is a temporary change in blood type
There is also a permanent change in blood type
For example, suffering from blood diseases such as leukemia
Transplantation of bone marrow hematopoietic stem cells from someone else is required
New hematopoietic stem cells
They make batches of their own red blood cells
Replace your own red blood cells
Hisayuki Hisaya
The blood type is then converted to the donor's blood type
⑦
Some people have lustful thoughts in their heads
Or after a harmonious exercise
This will lead to a sneezing situation
- "Sexually Induced Sneezing"
Some scientists have studied it
7 men who sneeze during orgasm
and 139 patients who sneezed during sexual fantasies
Discover the reason for this phenomenon
It may be that the parasympathetic nerves are exporting information to Tintin
Occasionally, it goes wrong and is exported to other organs
Sneezes when the nose receives a signal of irritation
By the way, are you sneezing quietly?
See if you've burned your brain cells here?
If you are shocked, like, favorite, and retweet
