1. Self-introduction of the pancreas?
My name is the pancreas.
Is about the shape of a narrow tongue.
Is about 15 cm long.
Weighs about 85 grams.
2.My neighbor?
I am hidden behind the stomach, living deep but not shallow, where I lie quietly all day long.
behind the waist is the spinal column, as if a hard bed, the residence that is called crowded.
That the duodenum holds my head tightly.
my head is also the access to the common bile duct, which is connected all the way to the 2nd segment of the duodenum, which is considered ecumenical
My tail is close to the spleen door, the spleen is injured and I often follow.
3. The structure of my body?
the fact that I am composed of two glands wrapped together.
glands consisting of many, many glandular vesicles.
Without me, sir, you will be malnourished, even if you eat mountains of food and seafood will not help.
4, my exocrine role?
I am the second largest chemical plant in the human body.
I play a key role for the digestive process.
I produce 700ml of digestive juices every day.
5. the alkaline digestive juices I make are used to neutralize stomach acid?
The chyme coming out of the gentleman’s stomach is acidic and the stomach acid will corrode the small intestine, fortunately I am there as an umbrella.
When the gentleman sits at the table, the signal is transmitted to thousands of glandular vesicles in my body.
Neutralizing stomach acid is nothing, there is more amazing than this.
6. I also produce three kinds of digestive enzymes?
I am also remarkable for making three highly competent enzymes.
Trypsin – which breaks down proteins into amino acids.
pancreatic amylase – converts starch into sugar
pancreatic lipase – breaks down fat into fatty acids and glycerol.
fortunately, I have more than enough capacity to secrete digestive juices, and 1/2 of the glandular follicles can do the job.
Even if my entire production system is destroyed, Mr. can live, because there is still intestinal fluid, bile, saliva, gastric juice to help, but live whether the happiness will be a big question mark.
7, my endocrine role is very important?
my most important task is to produce insulin.
If I do not secrete enough insulin, Mr. will get diabetes.
It was not until 1921 that humans extracted insulin from the pancreas of animals to cure diabetes. Before that, having diabetes was equivalent to having a terminal illness.
My body is like a “sea”, there are millions of “islets” like a group of cells – “islets “, each of which is a factory for insulin production.
Despite the large number of islets, they account for only 1.5% of my body weight, which shows how important they are.
(a) The trillions of islet cells in Mr. Body are highly efficient miniature furnaces – burning glucose and making energy.
Insulin is responsible for adding fuel to the furnace exactly as needed
8. What if something goes wrong with my body?
If my islets don’t listen and suddenly go on strike, Mr. cells will have to try to burn other fuels and fat will be burned off.
Mr. will become emaciated, hungry and starving (eat and drink more), bony and thin (lose weight)
The fat is not burned – it is excreted out of the body with urine, up to about 3800ml per day (polyuria).
9. I make insulin is also conditional?
If the gentleman eats too many sweets – I accelerate the production of insulin and fan the flames of the cellular furnace.
If the gentleman’s blood sugar is too low – I temporarily suspend insulin production to seal the furnace.
I also make glucagon in my body, which has the opposite effect of insulin, and insulin and glucagon both regulate each other.
10. I am vulnerable and have many concerns?
An uncivilized lifestyle, an uncivilized diet, so terrible that he not only hurts me, but mainly gives you, sir, diabetes that requires lifelong treatment.
that although there are now artificial insulin injections and sir can live, it is too uncomfortable to live
although there are now islet transplants, pancreas transplants, which can replace me, dangerous not to mention, but how it is not as good as the original
abdominal trauma that can rupture and bleed my body and injure my spine – I am sometimes implicated
gastrointestinal and biliary surgery, I am also susceptible to accidental injury, who called me their neighbor
Mumps, too, often pulls me in as a companion, unfortunately.
I am most worried about getting severe pancreatitis, slight to be taken seriously, as he can easily threaten the life of Mr.
My disease, if I need surgery, is quite difficult, please take me to a hospital that has the conditions, please give me medical treatment.
