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:
A few days
- Intestine – The intestine is one of the hardest working repair specialists, renewing all cells every two to three days.
- Taste Buds - Ever taken a sip of coffee a little too quickly? Then you’ll know what burnt tongue feels like. The average human has over 10,000 taste buds on the tongue which renew themselves every 10 – 14 days. Just think of all the food you consume in this time – this is certainly a good thing!
A few months
- Red Blood Cells – The average woman contains 4,600,000 red blood cells per cubic millimetre. It can take up to three months to replace each and every one.
- The Liver – Livers have a cell lifespan of around 5 months, before the renewing process must take place.
