Answer 5 out of 6 questions correctly.

If a person's body is damaged, the body can often heal itself. But sometimes, disease or injury can cause damage that is too severe to heal. When a limb is too severely damaged to heal, it may need to be amputated, or removed.

For example, a doctor can treat an infected limb with medicine. But if the infection does not go away, it can spread to the rest of the person's body. To stop the infection from spreading, the infected limb may need to be amputated.

In other cases, when a limb is badly injured, the skin, bones, muscles, and nerves may be severely damaged. If the damaged tissue cannot heal, it may die. The severely damaged or dead tissue then needs to be amputated.

Why might a person have a limb amputated? Select all that apply.
