It's a very rare feature on the back. Some people believe that back dimples are genetic like, a cleft chin. Men love to place their fingers in them as they are holding women.Then there are those who believe that it can be achieved through exercise (given the fact that most people with this feature have lean bodies).
When you inhale, your diaphragm contracts and moves down, making  more space in your chest. Air rushes in to fill this space, and you  inhale. When you exhale, your diaphrag â¦ m relaxes and moves up,  squeezing the carbon dioxide out of your body. 46 people found this useful.
During inhalation the diaphragm muscle contracts and this causes it to (effectively) move downwards, its previously upwardly curving shape becomes a flatter one, and this decreases the pressure in the thorax region (the region in which the lungs reside) because there is more air space.he diaphragm is a muscle and when it expands, it creates a negative pressure in the lungs, this make the air outside (which has a relative positive pressure) want to flow int â¦ o the lungs and maintain equilibrium.
