People live by breathing fresh air, fish breathe oxygen in water and trees absorb carbon dioxide. Everyone needs to breathe, but what they breathe is different. Without breath, there is no life.
People breathe all the time and can't stop for a moment. Once they stop, it means the end of life. Fish can't live without water for a while, and they will die without water. Life grows by breathing, and there is no life without breathing. Pay attention to miscellaneous diseases of traditional Chinese medicine and share health preservation methods with you.
Breathing is like eating, drinking, sleeping and blood circulation. The human body must be renewed and kept alive. Breathing is to absorb oxygen in space. With oxygen, cells can carry out aerobic breathing, mitosis and self-renewal, so people should keep breathing fresh air.
I am not surprised that people need to breathe. I wonder why people have secular desires. If people don't have sexual desire, they don't have to find a partner, girlfriend, marriage and love ... Without the desire for the opposite sex, they don't have to work so hard to make money, marry and have children and support their families. There won't be so many people who commit crimes because of emotional problems.
When people breathe, it is caused by the difference between lung pressure and external pressure. When lung pressure is high, they will exhale. When the air is exhausted, the lungs are depressed, and when it is lower than the external pressure, they will inhale. Breathing in the lungs can also be regulated by intercostal muscles. In the middle of the chest and abdomen, the diaphragm can control the breathing rhythm to some extent through the diaphragm and intercostal muscles, while human children have (autonomic nerves). I forget what it's called. If it is out of control, it will make you continue to breathe, and at the same time, the high external pressure will also suck air into your lungs, and then you will start breathing again.
Breathing refers to the necessary process of gas exchange between the internal and external environment of human body. The human body inhales oxygen and exhales carbon dioxide through breathing, thus maintaining normal physiological functions.
Physiologically speaking, the process of eating, digesting and being absorbed by the human body all needs blood transportation to complete. The transportation of blood requires inhaling oxygen and exhaling carbon dioxide. People's lungs have a fixed volume. You can't keep breathing without breathing. Breathing is the condition for the body to carry out metabolism. When breathing stops, people's brain and heart are first ischemic, which is also called hypoxia death. So breathing is as important as inhaling. There is no distinction between important and unimportant. They can't be separated.
