During respiration, the diaphragm moves upwards and returns to dome shape from the flattened shape before during expiration.
This movement of diaphragm can decrease the lung volume, increase the pressure inside and thus force the air out. This process is expiration.

Adaptation, inherited traits that increase an organism's chance of survival, also determine an organism's niche.
Adaptations are features or behaviors exhibited by organisms and are usually common in a population. Adaptations evolve by natural selection and they fit organisms to their environment. Adaptations have functional roles and may be physiological, structural or behavioral. The long necks of giraffes for feeding in the tops of trees, and the long canine teeth of carnivores are examples of adaptation.
