Explanation:

In medicine, injury is a non-specific term used to describe any damage or abnormal change in the tissue of a living organism. Such anomalies can be caused by illness, trauma or simply by playing sports, for example.

When an injury occurs it is important that it be treated as quickly as possible, avoiding complications and allowing faster healing, providing greater comfort to the victim. As you can see the treatment of injuries must be established quickly, for this reason, it is necessary that you learn to treat an injury before it happens because that way you will be ready to act when any injury happens to you or someone close to you.
