human body cells and bacteria

human body cells and bacteria

human body cells and bacteria:





About 32 million bacteria call every inch of your skin
Germaphobes don't need to worry however , as a majority of these are entirely harmless and some are even help full in maintaining a healthy body.


Human 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 mouth 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.

Three hundred million cells in the human body every minute
While that sounds like a lot, its 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.

Humans shed about 600000 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

Every day an adult body produces 300 billion new cell
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

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

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 the high levels of this iron  out of the body, you'd have enough to make a small nail and very severe anemia

The most common blood  type in the world is type O
Blood blanks find it valuable as it can be given to those with both 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

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 explain why the lips appear pale when a person is anemic or has lost -

internal organs of human body and their functions

internal organs of human body and their functions

internal organs of human body and their functions:




Internal Organs


  • The largest internal organ is the small intestine.
  • Despite being called the smaller of the two intestines your small intestine is actually four times as long as the average adult is tall. If it weren't looped back and forth upon itself it wouldn't fit inside the abdominal cavity.



  • The human heart creates enough pressure to squirt blood 30 feet
  • No wonder you can feel your heart beat so easily . Pumping blood through your body quickly and efficiently in the strong contractions of the heart and the thick walls of the ventricles which push blood to the body



  • The acid in your stomach is strong enough to dissolve razor blades .
  •  While you certainly shouldn't test the fortitude of your stomach by eating a razor blade or any other metal object for that matter , the acids that digest the food you eat aren't to be taken lightly . Hydrocholoric acid the type found in your stomach is not only good at dissolving the pizza  you had for dinner but can also eat through many types of metal



  • The human body is estimated to have 60,000 miles of blood vessels .
  •  To put that in perspective the distance around the earth is about 25000 miles making the distance your blood vessels could travel if laid end to end more than two times around the earth.





  • You get a new stomach lining every three to four days . The mucus-like cells lining the walls of the stomach would soon dissolve due to the strong digestive acid takes it toll o the lining of your stomach.




  • The surface area of a human lung is equal to a tennis court . In order to more to more efficiently oxygenate the blood the lungs are filled with thousands if branching bronchi snd tiny grape-like alveoli . These are filled with microscopic capillaries which oxygen and carbon dioxide . The large amount of surface area makes it easier for this exchange to take place and makes sure you stay properly oxygenated  at all times .



  • Women's heart beat faster than men's .
  • The main reason for this is simply  that on average women tend to be smaller than men and have less mass to pump blood to. But women's and men's hearts can actually act quit differently , especially when experiencing taruma like a heart attack and many treatments that work for men must be adjusted or changed entirely to work for women.




  • Scientists have counted over 500 different liver functions.
  • You may not think much about your liver except after a long night of drinking but the liver is one of the body's hardest working largest and busiest organs . Some of the functions your liver performs are ;production  of bile decomposition of red blood cells plasma protein systhesis and detoxification.



  • Your left lung is smaller than your right lung to make room for your heart
  • For most people , if they were asked to draw a picture of what the lungs look like they would draw both  looking roughly the same size. While lungs are fairly similar in size, the human heart  though located fairly centrally is  tilled slightly to the left making it take up more room on that side of the body and crowding out that poor left lung.




  • You could remove a large part of your internal organs and survive . The human body may appear fragile but it's possible to survive even with the removal of the  stomach the spleen , 75% of the  liver 80% of the intestines, one kidney one lung and virtually every organ from the pelvic and groin area . You might not feel too great but the missing organs wouldn't kill you ..


Aging and Death

Aging and Death

Aging and Death:





  • The ashes of a cremated person average about 9 pounds..
  • A big part of what gives the human body weight is the water trapped in our cells . Once cremated , that water and a majority or our tissues are destroyed leaving little behind.



  • Nails and hair do not continue to grow after die
  • They do appear longer when we die however as he skin dehydrates and pulls back from the nail beds and scalp




  • By the age of 60 , most people will have lost about half their tste buds.
  • Perhaps you shouldn't trust your grandma's cooking as much as you do. Older individuals tend to lose their ability to taste , and many find that they need much more intense flavoring in order to be able to fully appreciate a dish.




  • Your eyes are always the same size from birth but your nose and ears never stop growing.
  • When babies look up at you with with those big eyes , they're the same size that they'll be carrying around in their bodies for the nest of their lives . Their ears and nose however will grow throughout their lives and research has shown that growth peaks in seven year cycles.



  • By 60 years of age, 60% of man and 40% of women will snore .
  • If you've ever kept awake  by a snoring loved one you know the sound can be deafening . Normal snores average around 60 decibles the noise level of normal speech intense snores can reach more than 80 decibles the approximate level caused by a jackhammer breakig up concrete.



  • A baby's head is one-quarter of it's total length but by the age 25 will only be one-eighth of its total length.
  • As it turns out our adorably oversized baby heads won't change size as drastically as the rest of our body. The legs and torso will lengthen, but the head won't get much longer



diseases and injuries

diseases and injuries

diseases and injuries:



Monday is he day of  the week  when the risk of heart attack is greatest. Yet  another reason to loathe Mondays! A ten year study in Scotland found that 20% more people die of heart  attacks on Mondays than any other day of the week Researchers theories that it's a combination of too  much fun over the weekend with the stress of going back to work that causes the increase


Humans can make do  longer without food than sleep.
While you might feel better  prepared to stay up all night partying than to  give up eating that feeling will be relatively short lived. Provided there is water , the average human could survive a month to two months without food depending on their body  fat and other factors . Sleep deprived people however start experiencing redical changes after only a few sleepless days . The longest recorded time anyone has ever gone without sleep is 11 days at the end of which the experimenter was awake but stumbled over words hallucinated and frequently forgot what he was doing.

Simple moderately severe sunburn damages the blood vessels extensively.
How extensively? Studies months for them to return to their normal condition . Consider that the next time you're feeling too lazy to apply sunscreen before heading outsides .

Over 90 % of diseases are caused or complicated by stress.
That high stress job you have could be doing more than just wearing you down each day. It could also be increasing your chances of having a variety od serious medical condition like dipression , high blood pressure and heart disease


A human head

remains conscious for about 15 to 20 seconds  after it is been decapitated .
While it might be gross to think about the blood in the head may be enough to keep someone alive and conscious for a few  seconds after the head has been separated from the body though reports as to the accuracy of this are widely varying.

hair and nails facts:




Hair And Nails

Facial  hair grows faster than any other hair on the body.
If you're ever had a covering of stubble on your face as you're clocking out at 5 o'clock you're probably pretty  familiar with this. In fact if the average man never shaved his beard it would grow to over 30 feet during his life time , longer than a killer whale.



Every day the average person loses 60-100 strands of hair .

 Unless you're already bald, chanced are good that you're shedding pretty heavily on a daily basis . Your hair loss will vary in accordance with the season , pregnancy, illness diet and age


Women hair is about half diameter of men's hair .
While it might sound strange, it shouldn't some as too much of a surprise tht men's hair should be coarser than that of women. Hair diameter also varies on avergae between races making hair plugs on some men look especially obvious .



One human hair can supports 3.5 ounces
That's about the weight of two full size candy bars, and with hundreds  of thousands of hairs on the human head, makes the tale of Rapunzal much more plausible

nails facts



The fastest growing nail is on the  middle finger .
And the nail  on the middle finger of your dominant hand will grow the fastest of all. Why is not entirely known, but nail growth is related to the length of the finger , with the longest fingers growing nails the fastest and shortest the lowest.


There are as many hairs per square inch on your body as a chimpanzee..
Humans are not quite nakes apes that we're made out to be. WE have lots of hair, but on most of us, iit's not obvious as a majority of the hairs are too fine or light to be seen


Blondes have more hair.

They're said to have more fun, and they definitely have more hair. Hair color determines how dense the hair on your head is. The average human has 100000 hair follicles , each of which is capable of producing 20 individual hairs during a person's life time. Blondes average 146000 follicles while people with black hair tend to have about 110000 follicles . Those with brown hair fit the average with 100000 follicles and redheads have the least dense hair with about 86000 follicles .


Finger nails grow nearly 4 times faster than toe nails .

If you notice that you're trimming your finger nails much more frequently than your toe nails you're not just imagining it . The nails that get the most exposure and are used most frequently grow the fastest . On average nails on both the toes and fingers grow about  on tenth of an inch each month .



The lifespan of a human hair is 3 to 7 years on average..
While you quite a few hairs each day, your hair actually have a pretty long life providing they aren't subject to any trauma. Your hairs will likely get to see several different hair cuts , styles and even possibly decades before they fall out their own


Human hair is virtually indestructible.

Aside from it's flammability, human hair decays at such a slow rate that it is practically non-dis integrative . If you're ever wondered how your  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 chemical
