Hello everyone,

 

Quick question. When diaphragm contracts, it must contract all the abdominal organs like liver and stomach. When this happens constantly wouldn't it damage these organs. Thanks :)

The Diaphragm doesn't move up and down that much, at least, not enough to cause severe contraction of the abdominal organs.

The chest cavity expands outwards and upwards to fill with air. If you lie on your back and breath this movement is more obvious.

There's not an increase in pressure, not a noticeable one, since the lung is open to the atmosphere.
