Quiz Yourself to Grow What You Know About Regeneration
Regeneration is the natural process of replacing or restoring cells that have been lost or damaged due to injury or disease. A few animals can regrow entire organs or other body parts, but most have limited abilities to regenerate.
Scientists
in the field of regenerative medicine study how some animals are able to
rebuild lost body parts. By better understanding these processes and learning
how to control them, researchers hope to develop new methods to treat injuries
and diseases in people.
Take this quiz to test what you know about regeneration and regenerative medicine. Then check out our Regeneration fact sheet and the regeneration issue of Pathways , a teaching resource produced in collaboration with Scholastic.
