Definition of Distention

Distention: The state of being distended, enlarged, swollen from internal pressure.

For example, on inhalation there is distention of the lungs due to the increased air pressure within the lungs.

The word "distention" comes from a Latin root "tendere," to extend. The word "tendon" comes from the same root.
