Weird Human Body Facts
The human body is an extremely complex and intricate system, some weird facts about human body.
100.The indentation in the middle of the area between the nose and the upper lip has a name. It is called the philtrum. Scientists have yet to figure out what purpose this indentation serves, though the ancient Greeks thought it to be one of the most erogenous places on the body.
79.Bone is stronger than some steel. This doesn't mean your bones can't break of course, as they are much less dense than steel. Bone has been found to have a tensile strength of 20,000 psi while steel is much higher at 70,000 psi. Steel is much heavier than bone, however, and pound for pound bone is the stronger material.
80.The feet account for one quarter of all the human body's bones. You may not give your feet much thought but they are home to more bones than any other part of your body. How many? Of the two hundred or so bones in the body, the feet contain a whopping 52 of them.
85.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.
89.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 anemic 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.
81.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.
53.After eating too much, your hearing is less sharp. If you're heading to a concert or a musical after a big meal you may be doing yourself a disservice. Try eating a smaller meal if you need to keep your hearing pitch perfect.
7.Neurons continue to grow throughout human life. For years scientists and doctors thought that brain and neural tissue couldn't grow or regenerate. While it doesn't act in the same manner as tissues in many other parts of the body, neurons can and do grow throughout your life, adding a whole new dimension to the study of the brain and the illnesses that affect it.
2.The brain operates on the same amount of power as 10watt light bulb. The cartoon image of a light bulb over your head when a great thought occurs isn't too far off the mark. Your brain generates as much energy as a small light bulb even when you're sleeping.
21.Human hair is virtually indestructible. Aside from it's flammability, human hair decays at such a slow rate that it is practically nondisintegrative. If you've ever wondered how your how clogs up your pipes so quick consider this: hair cannot be destroyed by cold, change of climate, water, or other natural forces and it is resistant to many kinds of acids and corrosive chemicals.
