Why people are not flattened by atmospheric pressure

The atmospheric pressure is kept around us, and the pressure inside us is enough to cancel it out, so we can keep the shape, and the same is true of the bread, and the gases inside keep it in shape. Just like a balloon, if you release the air, it has no shape, only the internal air pressure is enough to inflate the plastic skin, in order to offset the atmospheric pressure (of course, not only the pressure of the internal gas, but also the material of the skin, etc.), but the internal air pressure is too large to burst, that is, the external air pressure is no longer enough to offset the internal air pressure of the balloon, and the air pressure difference is not enough to be offset by ......the balloon skin

Actually, you will also be compressed, by pressure from the inside, and from the outside atmospheric pressure, and other pressures, find a balance, your nervous system will not feel it, if you add something else such as a brick, you will feel it.

You have to use the iron plate to compare the state of balance between the internal and external atmospheric pressure, but you have to take this iron plate apart and disassemble it into a lot of fine things"Small iron plates"Until it becomes a disassembled molecule, it enters the inner and outer layers of each cell and presses the cell membrane in pairs from the inside out. Outside"Iron plate"It's the atmosphere, and the iron plate inside is your cell fluid. When you say they are all under equal pressure, can you feel the pressure?

It is due to the fact that the air pressure in the human body is equal to the atmospheric pressure, and the force cancels out, not the atmospheric pressure in the palm and back of the hand, which cancels out.

If you have the same atmospheric pressure in your body as you do outside, and the atmospheric pressure inside and outside is equal, you won't be flattened.

The two iron plates you are talking about pressing a person from opposite directions, in that case the force point is only on one side, and then it will definitely be flattened.

Because the pressure in the human body is basically the same as the outside air pressure. For example, if you put an empty (thinner) plastic bottle in water, it will be flattened by water, but if you fill the bottle with water, it will not be flattened when you put it in water.

Two iron plates are just two directions. The atmospheric pressure is omnidirectional.

Not from the top down. Osmotic pressure in the human body is naturally formed. If you go to a place with low pressure, it will be very uncomfortable, such as going to a high altitude.

There will be altitude sickness. If the air pressure is equal to zero, there will be no life. Doesn't God 6 have a pressurized chamber, and when you go out of the space chamber, you also need to pressurize your clothes.

I don't understand you holding the egg yet. It is difficult to crush an egg with your hands, if you squeeze it with two iron plates. It shatters in one fell swoop.

The pressure of the human body is equal to the pressure of the atmosphere outside the body.

It is very simple that people are born and raised under this atmospheric pressure, it can be said that the atmosphere is a container, and the pressure given by the atmosphere is all-round, will people still be flattened!

Because there is air with the same air pressure as the outside in the cranial cavity, chest cavity, and abdominal cavity, and most of the human tissues are water, the air pressure has little effect on the water, so the human body can withstand the pressure of about 1 atmosphere. If the pressure is high, the person will suffocate to death because he can't breathe in the air, and if the air pressure is low, the person will suffocate because he can't breathe out the air.

The space where people live is surrounded by air, not only the outside of the human body has atmospheric pressure, but also the inside of the human body, under normal circumstances, the pressure generated by the atmosphere inside and outside the human body is equal, so people will not be flattened.

If you have money, you can't be flattened anywhere, let alone the atmosphere.

Living in this society, everyone has pressure. Our stress comes from different factors, there is pressure in life and there is pressure in work. But these are all mental pressures, and today we're going to talk about real pressures, which are our atmospheric pressures.

The air fills our surroundings and makes us not feel their presence or even think they are weightless. Actually, this is not the case, air has weight, it is made of different kinds of gases.

The air is filled with a wide variety of gas molecules, with nitrogen molecules accounting for the largest proportion and then oxygen molecules. Although these gases are made up of molecules, molecules also have mass.

According to scientists, a standard atmospheric pressure is about 1 kilopascal, which is like a car pressing on your head. If the atmospheric pressure is so great, why aren't we squashed?

This is due to the balance in our body. While the external gas molecules exert great pressure on the body, there is also a force in the body that is the same size and opposite to the opposite direction, and they constitute a pair of balanced forces.

And the reaction force inside the body is the sum of all the organs of the human body, if there are no organs in a person's body, then the human body will be under atmospheric pressure**. Only when there is no pressure difference between the inside and outside can the human body maintain its normal shape.

Because the internal and external interaction forces are balanced, the human body does not feel the burden of atmospheric pressure。Moreover, all organs in the body have the same atmospheric pressure, which ensures that there is no pressure difference between the whole body and the outside world, so our body will not happen**, and we will not feel the pressure of the atmosphere.
