Under normal inspiration the chest wall stays relatively still, only the abdomen moves because of diaphragmatic motion. However, when you take a deep breath the intercostal muscles and the scalene muscles contract. This causes the chest wall to expand outward(due to the intercostals) and move upwards(due to the scalenes).
When exhaling, the diaphragm relaxes and moves upwards, causing a decrease in the volume of the chest cavity. This increase in pressure pushes air out of the lungs.
Earthquakes that causes most damage when two plates crashed and one plate moves upwards vertically than the other plate.
During inhalation, the diaphragm contracts and moves downwards, causing the chest cavity to expand and draw air into the lungs. During exhalation, the diaphragm relaxes and moves upwards, allowing the chest cavity to decrease in size and push air out of the lungs. These movements ensure proper ventilation of the lungs.
the chest moves front and back

Paralysis is most often caused by damage in the nervous system, especially the spinal cord. Other major causes are stroke, trauma with nerve injury, poliomyelitis, botulism, spina bifida, multiple sclerosis, and Guillain-Barré syndrome. Temporary paralysis occurs during REM sleep, and dysregulation of this system can lead to episodes of waking paralysis. Drugs that interfere with nerve function, such as curare, can also cause paralysis. There are many known causes for paralysis, and perhaps more yet to be discovered.Pseudoparalysis (pseudo- meaning "false, not genuine", from Greek ψεῦδος[6]) is voluntary restriction or inhibition of motion because of pain, incoordination, orgasm, or other cause, and is not due to actual muscular paralysis.[7] In an infant, it may be a symptom of congenital syphilis.
When you breathe out the diaphragm moves upwards to push the air out of the lungs. When you breathe in the diaphragm moves downwards to draw air into the lungs. When you breathe out your diaphragm contract and moves upwards towards your head. when you breathe in too much your diaphragm explodes
Your lungs deflate nad you breathe out
When you breathe in, your diaphragm moves down and your rib cage expands to allow more air into your lungs, causing your chest size to increase. This expansion of the chest cavity allows the lungs to fill with air, providing oxygen to the body and facilitating the exchange of gases in the respiratory system.
When an object is moving upwards, its velocity is directed upwards. If the object is near the Earth or any other planet, then its acceleration is directed downwards, which also means that its upward velocity is decreasing.
During inhalation, the diaphragm contracts and moves downward, increasing the volume inside the chest cavity. This increase in volume causes a decrease in pressure, leading to air rushing into the lungs to equalize the pressure. As a result, the chest expands to accommodate the incoming air.
