What happens to a severed arm below the elbow?

When an arm is severed below the elbow, the immediate consequences include severe bleeding and potential shock due to blood loss. The nerves, muscles, and bones are damaged, leading to loss of function in the hand and wrist. If the severed part is preserved properly and medical intervention is prompt, there may be possibilities for reattachment or reconstruction, but outcomes vary significantly based on the injury's severity and timing of treatment.
