A severed limb refers to a body part that has been cut or torn off from the rest of the body. This can occur as a result of accidents, trauma, or medical procedures.

The severed limb should be kept cool and transported with the injured person to the hospital as quickly as possible for reattachment or other necessary medical treatment.
