1. to pull back quickly, such as towards a resting position upon removal of a strong opposing force.
2. (re´koil) a pulling back quickly.
elastic recoil the ability of a stretched elastic object or organ, such as the lung or bladder, to return to its resting position. See also elastance.

elastic recoilThe inherent resistance of a tissue to changes in shape, and the tendency of tissue to revert to its original shape once deformed. A sensitive indicator of elastic recoil (ER) is the coefficient of retraction—the ratio of the maximal static recoil pressure to total lung capacity. ER is the effective pressure driving maximal expiratory airflow, and is increased after lung-reduction surgery for severe emphysema. The ER of lungs is directed centripetally and the lungs have a tendency to deflate, while the ER of the chest wall is directed centrifugally, favouring an increase in lung volume; the sum of the opposing ER of the lungs and the chest wall generates a subatmospheric pressure of -5 cm H2O.
