Open wound
An open wound is an injury involving an external or internal break in body tissue, usually involving the skin. Nearly everyone will experience an open wound at some point in their life. Most open wounds are minor and can be treated at home.
Falls, accidents with sharp objects or tools, and car accidents are the most common causes of open wounds. In the case of a serious accident, call 911 or seek immediate medical attention, particularly if there’s a lot of bleeding or if bleeding lasts for more than 20 minutes.
There are four types of open wounds, which are classified depending on their cause.
