How our bodies repair themselves

The Human Body is wonderful thing, handling the majority of every day functions as we go about our daily lives. Think about it – Our bodies require oxygen, which is handled by our lungs without us even sparring a thought to do so. As you read this article, you’re not thinking “I must breathe in, now I must breathe out” or “I must now pump blood to my left arm.”

The same can be said for a whole host of things, including the repair of our bodies cells. So how often do our body parts renew themselves? Check out the following shortlist provided by the folks at the Healthy Hideout to find out:
