Why are our bodies not crushed by the pressure of the atmosphere?
I believe it's because we have the atmosphere inside us as well as outside us. So the effect of the pressure of the atmosphere pressing down on us is counteracted by the pressure of the atmosphere inside us pushing out.
The entire human body, including all the bones, tubes, sacks, and fluids in it, is constructed to develop an outward pressure that compensates for the inward atmospheric pressure. Air pressure at ground level does not hurt us because, over the thousands of years of evolution, the human body has developed in the presence of that pressure and has evolved to equalise it from pressure produced internally by the human heart and the various solid structures like bones etc.
Because there is air in the blood and the tissues of the body, and the pressure therefore acts outwards as well as inwards. Fish could not live in the depths of the ocean if there were not a similar balancing of pressure inside their bodies.
