word | occlusion |
---|---|
definition | An obstruction or blockage; the act of obstructing or closing off. |
eg_sentence | The doctors worry that a loosened piece of plaque from the artery wall could lead to an occlusion of a brain artery, resulting in a stroke. |
explanation | Occlusion, formed with the prefix ob-, here meaning “in the way,” occurs when something has been closed up or blocked off. Almost all heart attacks are the result of the occlusion of a coronary (heart) artery by a blood clot, and many strokes are caused by an occlusion in an artery serving the brain. When a person's upper and lower teeth form a malocclusion, they close incorrectly or badly. An occlusion, or occluded front, happens when a fast-moving cold front overtakes a slow-moving warm front and slides underneath it, lifting the warm air and blocking its movement |
