Yang Tian quickly absorbed knowledge in the system space, and the middle-aged man's patience on the podium gradually wore out. Pen % fun % Pavilion www.biquge.info

The design of the classroom has always been intriguing, and the students below will never know that the teacher stands on the podium with a wide view and can see it at a glance.

The students below are secretly playing with their mobile phones, and even sleeping with their heads propped up, when he can't see, hey!

The middle-aged man only felt that he was suffocating a breath of stuff in his chest.

He is also a teacher who has been teaching at Oriental Medical University for many years, and when he stood on the podium, he was also wearing a military uniform, and the moment when he took off his military uniform a few years ago and his tears were still clearly visible, but why did the students below change so much?

At the beginning, those students, dressed in neat military uniforms, were close to each other, everything was in order, and they were more serious than anyone else in class, even if they were tired from the emergency training in the middle of the night, they would at most "nod" sleep, and there would never be such a bad situation as playing with mobile phones!

Well, it seems that the army has to collect mobile phones, and they can't play......

Soldiers who have been in the army for a long time always look down on the laziness of local university students to some extent, and although the middle-aged man has taken off his military uniform for many years, he still can't change the thing in his bones.

"Higher animals, including human tissues and organs, are highly differentiated and have their own functional and metabolic characteristics. To maintain the normal function of the body and adapt to the changes in the internal and external environment of the collective, it is not only necessary to coordinate the metabolism of various substances in the cells between tissues and organs......"

The middle-aged man followed the content of the textbook, but his eyes were always on those key goals.

One is already "nodding", and the one who is in a trance is not particularly stable.

The other has already set up a textbook, I am afraid that he will see that he has no practical action due to the thunder and rain, and he is ready to commit crimes against the wind.

As for the one who has been lying on the table, he hasn't moved at all after half a class!

"Classmates." The middle-aged man suddenly stopped his lecture and took a deep breath.

This is no longer a military academy, and the officers and soldiers sitting below are no longer officers and soldiers who can tolerate your training and dare not complain, but a group of lazy half-sized boys.

He couldn't beat or scold, so he had no choice but to use the tricks that the elementary school teacher was using.

"I'm asking you a question."

Ask questions!

It's the best way to get attention.

It's a pity that the middle-aged man's effect has failed, except for a few people who have been following the progress of his lecture and listening carefully to the lecture at a glance, the rest have no reaction at all!

"Ahem! Students! ”

The middle-aged man's voice was so plain and unrecognizable that no one even reacted to his wrongness.

The students in the audience still take care of each other, those who play with their mobile phones continue to play with their mobile phones, those who talk about love continue to be affectionate and loving, those who sleep have already posed, and Yang Tian still hasn't moved a finger.

"Students!"

"Bang!"

A loud bang resounded through the loudspeaker throughout the classroom, and everyone finally woke up and looked at the middle-aged man in horror.

"I'm asking you a question."

The middle-aged man cleared his throat and knocked on the podium twice, completely waking up those who were sleeping, and then he spoke, "Everyone knows glucagon and insulin, right?" ”

"Yes."

Everyone didn't know why, but they spoke in unison.

These two things, these two hormones to be exact, have been exposed to since junior high school biology class.

Glucagon, as the name suggests, is a hormone secreted by the pancreas that raises blood sugar.

Insulin is also a hormone of the pancreas, but only a specific part of the pancreas, that is, the "islets", can secrete, and the action of glucagon is antagonistic, it is hypoglycemic.

There are many hormones that raise blood sugar in the human body, in addition to glucagon, there are adrenaline, thyroxine and so on, but there is only one hormone that lowers blood sugar, that is, insulin.

This is why hypoglycemia can be treated in many ways, but hyperglycemic disorders are often particularly intractable.

The main component of insulin is protein, and its target cells are somatic cells that are found throughout the body, which means that almost all cells in a person's body can be controlled by insulin.

Once the insulin has spoken, "You all lower my blood sugar!" All the cells must obediently obey his command, grab the excess glucose in the blood, or fix it, or let it be converted into other substances, so that the glucose in the blood will be less and less.

When it comes to insulin, you can't talk about diabetes.

With the development of society, economic progress, the improvement of people's living standards, the quality of diet is also improved, irregular diet or wrong diet often appears on people's tables, and the "three highs" are quietly coming.

The three highs are high blood sugar, high blood lipids, and high blood pressure.

Among them, the causes of hyperglycemia can be briefly divided into the following two types: insulin secretion disorders and insulin receptor disorders.

Insulin secretion disorder, that is, insulin cannot be produced normally in the human body, and he is not there when he is needed, and no one gives the order to "lower blood sugar", and the blood sugar will naturally be high.

Insulin receptor disorder, that is, insulin does not work, although he is there, but the cells do not listen to him, and blood sugar naturally cannot be lowered.

The diabetes caused by the former can also be treated by infusion of synthetic insulin, if you don't have it, I'll give it to you, right?

And the diabetes caused by the latter is more tricky, the bear children are disobedient, we are not their parents "outsiders", what can we do?

Students are naturally familiar with glucagon and insulin, but what do the teachers want to do when they ask about this at this stall?

The podium just now rang loudly, this is the rhythm of doing things?

The middle-aged man looked at the boys and girls in the audience with a confused look on his face, and couldn't figure out his intentions.

He finally regained the feeling of attending classes at the Eastern Medical University, which was still a military academy - at that time, the soldiers and brothers could not understand what he was talking about.

"Since my classmates know about glucagon and insulin, I'm going to ask a question."

The corners of the middle-aged man's eyes wrinkled, "If you answer correctly, it means that you have mastered the content of this class, then I don't need to lecture anymore, everyone can go back to the dormitory to rest after class now, okay?" ”

The audience cheered and let out a "good" in unison!

Everyone was jubilant, but the middle-aged man hooked the corners of his mouth, "But what if you can't answer?" ”

There was an instant silence below.

The middle-aged man's gaze swept over the faces of the people who were sleeping and playing with their mobile phones just now, and finally stayed on Yang Tian, who was still lying on the table, for a few seconds before he spoke.

"If you can't answer it, it means that you haven't learned everything and you can't sleep in my class! If I see the sleeping man again, I will see a person who has been dragging for half an hour! ”

"Shhhh

Suddenly there was a gasp for air.

I saw a drag hall for half an hour!

The middle-aged man speaks in a tone all the year round, and he can't help but want to sleep when he listens, plus he reads completely according to the book, and being able to come to class is a good shame for him!

If this is really delayed, it is difficult to ensure that no one sleeps for half an hour, one sleeps for another half hour, and the other for half an hour, and this hall will be taken off indefinitely......

It's not that the allies don't work hard, but the enemy is too strong!

"Okay, I'll take your promise, I'm going to solve the question!"

The middle-aged man looked victorious, turned around and wrote a line on the blackboard-
