Chapter 191 Studying Medicine
After guessing that the reason for the low sperm activity was the continuous strengthening of his own body due to the special reason of time travel, Li En resumed higher intensity and more scientific physical exercise methods.

He felt that if his physical fitness could quickly reach a certain level, perhaps this phenomenon would disappear.

Therefore, his diet has become very regular and healthy, and even the eating habits of his family have been changed. At first, he was a little uncomfortable, but after a long time, he enjoyed himself.

The father-in-law and mother-in-law are too old to do too much exercise, so they do some simple exercises with Ran Qiuye, and of course, after they exercise, Ran Qiuye will train some by himself.

In this way, the spiritual outlook of the whole family has improved to varying degrees.

In addition to these, Li En also started to learn medical skills, but after getting in touch with medical skills, Li En realized that there are so many medical skills.

People's energy is limited, even a famous doctor who is proficient in one subject is already very remarkable, let alone proficient in everything?

That's almost impossible.

However, although medical skills become the same as academics after reaching a certain level, it is necessary to learn from surface to point, and to make achievements by studying extremely subtle branches, but at least in terms of basics, and before a certain level of medical skills, it is still not enough. separated.

The first goal Li En set for himself was to master this part of knowledge that does not require subdivision of branches.

Of course, this starts with the basics.

The first contact with the modern medical foundation actually contains a lot of content.

Human anatomy, tissue, embryology, physiology, biochemistry, microbes and microbiology, parasitology, immunology, pathology, pathophysiology, pharmacology, toxicology, molecular biology, cell biology, epidemiology.

These are only basic hospitals. After learning about them, Li En decided to start with the first one, and gradually explore this basic medical system.

It was only after learning that I found out that it was interesting, first of all, it was the motor system.

What is the movement system, that is, bones, joints, and skeletal muscles provide key support for human movement.

Bone can be regarded as an organ, which is composed of bone tissue (bone cells, collagen fibers, and matrix), has a certain shape and structure, is covered with periosteum, contains bone marrow, and is rich in blood vessels, nerves, and lymphatic vessels.It can continuously carry out metabolism and growth and development, and has the ability to rebuild, repair and regenerate.

Li En remembered the martial arts in those fantasy novels, there is a way to make the bones regenerate continuously by hitting the bones and make them denser.

"It turns out that bones do have the ability to regenerate."

After finishing his work, he turned on the lamp and pretended to read a book with Ran Qiuye. In fact, Li En, who was fully focused on the [knowledge web page], was secretly surprised when he saw this page.

Then he looked down even more enthusiastically.

The more you look down, the more fascinated you are.

It wasn't until Ran Qiuye reminded him to go to bed that Li En suddenly realized the passage of time. He closed the book while closing the knowledge webpage, and went to sleep without continuing.

Just lying on the bed, I couldn't help but start thinking about those knowledge.

If a person wants to cultivate a good habit that can be persisted for a long time, the most important thing is to be able to see the gains.

The reason why many habits can't be persisted is because they can't see the gains and don't know what they can do after learning.

But work, which is obviously very annoying, has persisted. Why, isn't it because I know that I will be paid at the end of the month?

As long as you do something with a clear purpose, you will have a lot of motivation.

Now Li En is very motivated to learn medical knowledge in order to have a child.

After learning about the motor system, Li En began to understand the digestive system.

[Digestive system consists of two parts: alimentary canal and digestive glands]
[Clinically, the alimentary canal above the duodenum is often referred to as the upper alimentary canal, and the alimentary canal below is the lower alimentary canal]
Browsing the knowledge, Li En quickly focused on the first piece of system knowledge: the digestive tract.

Then came the lungs, pleura and mediastinum, all very interesting.

I don't know why, maybe it was forced by his illness, but Li En's learning progress was very fast.

After just three weeks, I have almost learned the knowledge of human anatomy.

Of course, this is just theory and I haven't tried it in practice, but...

Li En thought about the things he had to face, but in the end he decided to forget it. As the basis of system knowledge, a theoretical understanding is enough, and there is no need for practical operation.

He can't follow the example of Fan Jian's son Fan Xian to throw the grave...

Although with his relationship, it is not difficult to get a chance to practice, but his main purpose is not just this, so there is no need to waste too much time on this.

So, after Li En briefly thought about it, he put down [Human Body Anatomy] and started to tackle the next subject.

The next one is [organization]

Compared with the anatomy of the human body, histology is much simpler, and the content is not much, mainly introducing the four major tissues of the human body.

That is, epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

After this study, Li En just learned some more mysteries of the human body.

Epithelial tissue, also known as the epithelium, is an important structure lining or covering other tissues.It is composed of dense epithelial cells and a small amount of intercellular matrix.The structural feature is that the cells are tightly combined and the intercellular substance is less.

It usually has the functions of protection, absorption, secretion and excretion.Epithelial tissue can be divided into two types: covering epithelium and glandular epithelium.Epithelial tissue is the largest tissue in the human body.

After absorbing and learning a little bit of knowledge, Li En didn't feel bored at all, on the contrary, he was full of interest. [Organization] Learning from Li En only took three days to complete the strategy.

After that, [Embryology].

Li En learned that embryology is also called genetics, and its research contents include the gestation of life, the evolution process of embryos, the characteristics of morphological and physiological evolution at each stage of development, the adaptation, variation and inheritance of living conditions during development, and the relationship between individual growth and development. Unified laws of phylogeny, etc.Human embryology is a discipline that studies the development of the human body.

In a broad sense, it includes the gestation of life after the combination of sperm and egg (fertilization), prenatal development in the uterus during the embryonic and fetal periods, and all life from newborns, infants, children, adolescence to adulthood until aging and death. Postdevelopmental history.

The entire process of developing from a fertilized egg to an adult individual, and then entering aging and death is called ontogeny.

它包含下列两个发育阶段：生前（产前）发育：①精卵受精、卵裂至植入，为期2周：②胚胎期：第2～8周；③胎儿期：第3月至分娩出生。产后（产后）发育：①初生儿：从出生至生后2周；②婴孩期：从生后第3周至躯体直立（一岁左右）；③儿童期：从生后15个月至13岁，其中乳齿期2～6岁，恒齿期7～10岁，青春前期10～13岁，④青春期：14－20岁，由14～16岁开始青春发育至成熟；⑤成年期：25岁前骨胳系统骨化，生长基本完成，以后生长极慢；⑤衰老和死亡。

Li En had a brief understanding of this subject, and after spending a few days studying it, he did not continue to delve into it, and started to study [Physiology] instead.

Physiology was followed by biochemistry, microbes and microbiology, parasitology, etc. As time passed, Li En studied and progressed one by one.

In the blink of an eye, he entered the study range of [Immunology].

It's just that [Immunology] hasn't started for a long time, and the time has come to the end of May, and the delivery date of the agreed [-] sets of clothes has also arrived. Li En had to temporarily put down his studies and went to Guangzhou with the team.

In fact, [-] pieces of [-] pieces have already been shipped in batches, but it is just for the collection of the last payment and the completion of the cooperation with the first business, so Li En needs to visit the door in person.

I rushed to Guangzhou again, and when I arrived at the clothing store, Wang Jianyun's wife didn't show up. Instead, his ex-wife was by his side. After asking, he found out that she was pregnant.

Li En was speechless, why did he come to his side whenever he felt that something was going wrong?

"Mr. Li, this is the last final payment, a total of [-] and [-], please click."

As usual, it was before the bank, and after a few visits, both parties had tacitly agreed, and the deal was concluded directly through the bank, and several people were at ease.

Four million six thousand five hundred yuan is naturally not less, Li En smiled very satisfied after seeing the amount, and then went to a restaurant for dinner together under Wang Jiansheng's kind invitation.

"Mr. Li, we still sell a lot of clothes here, but most of them are work clothes and casual clothes. The profit is only a few yuan, but the quantity is large. Do you think you can do it?"

After three rounds of wine and delicious food, Wang Jiansheng naturally talked about business again. This time Li En naturally didn't hesitate, why not make money if he had money, and agreed directly.

Afterwards, some details were naturally discussed, and the business was finalized again. Li En also pondered whether he should open a clothing factory here.

Now the business plate is getting bigger and bigger, and it has been able to support the development of a factory here, and it can also save a transportation fee.

When the thought came up, Li En put it down again, and buried him in his heart, intending to save it for later thinking about it before it was too late.

Although it is more troublesome to transport here from Yiwu, but it happens to be able to develop our own transport fleet. Tomorrow's logistics is a huge cake. Wouldn't it be a good idea to try to develop it yourself before no one is sitting up?

But in this way, after going back, he had to adjust his position again.

"Mr. Li, to be honest, besides the clothing business, Wang is also more interested in the watch business."

When the clothing business was negotiated, Wang Jiansheng couldn't help but smiled and said to Li En: "I don't know about that watch, can you provide me with some more?"
