More knowledge~
Shaking the Three Views again~
My old fans should have been stored
A lot of "physiological knowledge"
(After all, they used to give science popularization to everyone)
Do you think you have little knowledge
Can you amaze everyone?
Then you will underestimate me
I've sorted it out for you again
7 Physiological Knowledge
Each is more ridiculous than the other
Let's have a look
①
I know you're shocked
Definitely not
Because this is rarely the case
The incidence rate is about one in five million
There is a professional term in medicine
It's called "Repeating the penis"
There are two reasons
Because in the process of embryonic development
Accidental error
Germ cells are formed twice
Genital malformation
So that one person has two Ding Ding
Some people are lucky
Not only one more
It can also have complete urethral structure
Able to urinate in turn or at the same time
But most deformed people
It's pretty miserable
Abnormal development of the second root
It's useless
It may even be accompanied by ejaculation disorder, infertility
It even affects bladder, kidney and other functions
②
Similar to male double ding
It is also abnormal during embryonic development
A kind of congenital malformation
But compared with male deformity
The twin uterus malformation of women is generally OK
As long as puberty is normal
Will not affect fertility
In addition, menstruation is affected by Internal endocrine Influential
Double uterus will not disturb endocrine
Therefore, menstruation of girls with double uterus is also normal
Some people even see gynecological diseases
Or when you're pregnant
I will know that I have double uterus through examination
③
Many people have heard of kidney transplantation
But few people know
Kidney transplantation is not to remove the bad kidney and replace it with the good one
But keep the original diseased kidney
Find another location and add a kidney
So there will be three kidneys in the body
The reason for doing so
Because the original kidney failed
But it still retains certain endocrine function
If you want to remove the diseased kidney
You need to open a cut about 15cm in size
And remove the 12th rib above the waist
To resect the diseased kidney layer by layer
This practice will cause more damage to the body
It's better to keep it without cutting
④
This is a very natural physiological phenomenon
be called "Gene Chimera"
When your mother was pregnant
You are not the only fertilized egg in the body
There are two or more
But when you grow and develop
Fuses other fertilized eggs into itself
Absorbed the nutrition of the compatriots
So when you were born
There are two sets of genes in the body
If you chime with germ cells
Then you may inherit
DNA of your father's siblings
Look for your "birthmark"
If there is a larger one
Maybe you absorbed other fertilized eggs
Let it become your "birthmark"
⑤
This is actually a technology
And very good
It's called "delayed interval delivery of multiple births"
Because under normal circumstances
Multiple births are all born together
Usually every one to several minutes
However, some people conceive multiple fetuses at different stages of development
One of them is not mature yet
Premature birth is prone to accidents
Therefore, if physical conditions permit
Doctors will consider using this technology
Of course, one of the most important things about having children is
No contractions
Still can't have a natural birth
So doctors can take advantage of this
After a pregnant mother gives birth to her first child
Artificial pause of uterine contraction
Let the second fetus not be born temporarily
⑥
"Blood type" refers to the type of antigen on the surface of blood components
But this thing is not fixed
Some special accidents
It will make you "change blood type" unconsciously
For example: carelessly scratch a wound
Leave it alone for a long time
Causing bacterial infection
Chemicals released by bacteria
Cause the antigen to be changed temporarily
Your blood type will be changed temporarily
This is a temporary change of blood type
Another condition is permanent change of blood type
Such as suffering from leukemia and other blood diseases
Need to transplant other people's bone marrow hematopoietic stem cells
New hematopoietic stem cells
Will produce batches of their own red blood cells
Replace your own red blood cells
in the course of time
The blood type will change to the donor's blood type
⑦
Some people have the idea of color in their minds
Or after a harmonious movement
Will cause sneezing
—— "Sexually induced sneezing"
Some scientists have studied
7 men sneezing during orgasm
And 139 patients sneezing in sexual fantasy
Find the reason for this phenomenon
It may be that when the parasympathetic nerve outputs information to Ding Ding
Occasional error, and output to other organs at the same time
When the nose is stimulated, it will sneeze
Say, are you sneezing quietly?
