Final answer:
A laceration is an injury where a blood vessel is severed causing blood and its components to leak out, usually due to a sharp blow.
Step-by-step explanation:
The meaning of laceration refers to a type of injury where a blood vessel is severed. When a laceration occurs, blood and blood components such as erythrocytes (red blood cells) and leukocytes (white blood cells) leak out of the breaks caused by the injury. It is typically the result of a sharp blow inflicted with a lot of energy, using tools that are quite sharp. Lacerations differ from other types of injuries such as dislocations, traumatic head injuries, bone breaks, or even bruises.
