Duction
Definition:
(n.) Guidance.

(20) Particular reference was placed on the active force generation test and the passive forced duction test.
Suction
Definition:
(v. t.) The act or process of sucking; the act of drawing, as fluids, by exhausting the air.
Example Sentences:
(1) The Cavitron Ultrasonic Surgical Aspirator (CUSA) is a dissecting system that removes tissue by vibration, irrigation and suction; fluid and particulate matter from tumors are aspirated and subsquently deposited in a canister.
(2) It is suitable either for brief sampling of AP durations when recording with microelectrodes, which may impale cells intermittently, or for continuous monitoring, as with suction electrodes on intact beating hearts in situ.
(3) During suction a flow of cold, dry room air replaces the warm, moist cavity air, causing cooling both directly and by vaporization of water.
(4) Suction mammaplasty can be used as a sole technique in congenital asymmetry or in post-reduction enlargement or asymmetry.
(5) If transportation is unduly delayed, immediate linear incision and suction may be of value.
(6) Suction blisters were raised on psoriatic lesions and normal appearing skin.
