A Brief History of Human Body (Ⅱ)

Yesterday, I shared with you the body, skin, brain and head of the human body (including eyebrows, eyes, ears, smell, mouth and taste). Each part has an irreplaceable role. Today, we will continue to learn the structure of the human body.

1. Heart? The weight of the heart is less than 65,438+0 pounds. How big your right fist is, how big your heart is. The heart beats 65,438+million times a day, up to 3.5 billion times in a lifetime. Before science was so advanced, people thought that the faster the heart beat, the better. No one else did. The heart is beating too fast, which is caused by high blood pressure and height, which is not a good thing. It only takes 50 seconds for the blood in your heart to save you a week. This speed is great.

2. liver? This is an early painless organ. Once it has pain, it will reach the late stage, and the situation will be particularly bad. The liver is the detoxification organ of human body, weighing about 1.5kg, and it can be regenerated. After cutting off 2/3, it can regenerate to its original size in a few weeks, but the long Zou Baba is not very beautiful. It is said that being angry is to punish yourself for the mistakes made by others. Because being angry hurts the liver, you can eat more green food.

3. The pancreas is located behind the stomach of the upper abdomen and is about 15cm long. At present, the three chronic diseases of human beings-diabetes-are pancreatic problems and abnormal insulin secretion. Why can't diabetics drink porridge? Because after drinking porridge, they will produce a lot of glucose in their bodies, and the ability of pancreas to metabolize and convert sugar will be weakened, which will lead to an increase in blood sugar. So diabetics also need to control their diet.

4. bones and muscles? The bones of the human body add up to less than 9kg, and most bones can withstand the pressure as high as 1 ton. The human body is mainly supported by muscles. * * * has more than 600 muscles, and the muscle loss rate is very high. For example, if you go to space 1 month, your muscles will lose 20%, so many soldiers will lose their muscles soon if they don't keep exercising after returning from the army.

5. The lungs and respiratory lungs breathe about 20,000 times a day, 7.3 million times a year, and about 550 million times a lifetime. Why does the epidemic now require everyone to wear a mask, because sneezing can fly 8 meters away and float in the air 10 minutes. And the longest continuous hiccups lasted for 67 years, and when he stopped hiccups one year later, he died. The lungs need us to eat more white ingredients, such as tremella and pears.

6. Digestion time of gastrointestinal women is longer than that of men, 55 hours for men and 72 hours for women. Moreover, there are more stomach diseases in China than in foreign countries, and there are also many intestinal diseases in foreign countries, because China eats more vegetables, which promotes the excretion of large intestine. Eating more meat abroad is harmful to the stomach at home and needs a balanced diet.

7. Spleen still magically helps you warm up. Why does the human body always stay between 36 and 38? No matter how high or low the outside temperature is, the temperature of the human body is always within this range. For example, drinking ice in summer, but the urine is still warm, indicating that the spleen is changing.

People who eat whole grains will inevitably have headaches and brain fever. This symptom of the body is actually similar to the one-click restart of the computer, which is self-repairing. If you manually press the keyboard of the computer during the restart process, it will cause the program to go wrong and the situation will get worse.

Human sweat is used to cool down, which is why humans can run so far, just like orangutans. They have long hair, and when they run, they will gasp, otherwise they will suffocate, and the human body will cool down by sweating.

Be familiar with your body. When you know what to do and what to eat is good for your organs, you will naturally live longer.

Being kind to yourself is one of the best manifestations of loving yourself.
