Some unseen ( microscopic) facts of body that u should know | amazing facts about the human body
Much of what takes place in our bodies happens at a level that we simply can’t see with the naked eye. These facts will show you that sometimes that might be for the best.
1. About 32 million bacteria call every inch of your skin home.
Germaphobes don’t need to worry however, as a majority of these are entirely harmless and some are even helpful in maintaining a healthy body.
2. Humans shed and regrow outer skin cells about every 27 days.
Skin protects your delicate internal organs from the elements and as such, dries and flakes off completely about once a month so that it can maintain its strength. Chances are that last month’s skin is still hanging around your house in the form of the dust on your bookshelf or under the couch.
3. Three hundred million cells die in the human body every minute.
While that sounds like a lot, it’s really just a small fraction of the cells that are in the human body. Estimates have placed the total number of cells in the body at 10-50 trillion so you can afford to lose a few hundred million without a hitch.
4. Humans shed about 600,000 particles of skin every hour.
You may not think much about losing skin if yours isn’t dry or flaky or peeling from a sunburn, but your skin is constantly renewing itself and shedding dead cells.
5. Every day an adult body produces 300 billion new cells.
Your body not only needs energy to keep your organs up and running but also to constantly repair and build new cells to form the building blocks of your body itself.
6. Every tongue print is unique.
If you’re planning on committing a crime, don’t think you’ll get away with leaving a tongue print behind. Each tongue is different and yours could be unique enough to finger you as the culprit.
7. Your body has enough iron in it to make a nail 3 inches long.
Anyone who has ever tasted blood knows that it has a slightly metallic taste. This is due to the high levels of iron in the blood. If you were to take all of this iron out of the body, you’d have enough to make a small nail and very severe anaemia.
8. The most common blood type in the world is Type O.
Blood banks find it valuable as it can be given to those with both type A and B blood. The rarest blood type, A-H or Bombay blood due to the location of its discovery, has been found in less than hundred people since it was discovered.
9. Human lips have a reddish color because of the great concentration of tiny capillaries just below the skin.
The blood in these capillaries is normally highly oxygenated and therefore quite red. This explains why the lips appear pale when a person is anaemic or has lost a great deal of blood. It also explains why the lips turn blue in very cold weather. Cold causes the capillaries to constrict, and the blood loses oxygen and changes to a darker color.
10.A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Moisture and grease on a finger result in fingerprints on surfaces such as glass or metal.
