The Human Body’s Ability to Repair Wounds

人体有很多的机制帮助我们维持生命, 其中之一就是伤口的自愈能力和组织的再生。

Among the numerous mechanisms that make human life possible is the body’s ability to heal wounds and regenerate damaged tissue.


The healing process is made possible by a cascade of complex cellular functions:

  • 血小板附着在伤口周围的组织,形成血凝块,然后把受损的血管壁补起来。
  • Platelets adhere to tissues around a wound, forming a blood clot and sealing damaged blood vessels.
  • 发炎能保护伤口免受感染,且可以移除因受伤而产生的细胞残骸。
  • Inflammation protects against infection and removes any “debris” caused by the injury.
  • 在几天之内,身体会开始再造新的组织替换受伤的组织,收缩伤口并修补受损的血管。
  • Within days, the body begins to replace injured tissue, make the wound contract, and repair damaged blood vessels.
  • 最后,会生成疤痕组织补强受伤的部位。
  • Finally, scar tissue remodels and strengthens the damaged area.
