Ten Things You Didn't Know About :- Yourself

It might sound like an insanely stupid question that I am answering ten things which even you didn't know about yourself.But is it really that foolish to say so.Read the following to find out!!

1.Which is the largest organ of your body?
"It must be the liver or the intestine or the pancreas".This will be the serious answer of a member of the general public who likes to exhibit his tremendous aptitude in biology.Did you just think so?Think again!!
The real answer is that it is neither the liver nor the intestine nor any organ with a mouthful name.It is the skin.
The weight of skin in an average adult is approximately 10.8 kg,which is 10 times more than the liver.
2.Your brain-
You lose 100000 brain cells everyday.But luckily,you have 100 billion altogether.The sad news is that the brain cells do not regenerate.That means,when you have lost too many,you are finished.If the surface of your brain could be stretched out,it would measure 2000 sq cm.
3.Find out how many pencils can be made from your body?
Your body has enough carbon to fill 900 pencils,enough fat to made 75 candles, enough phosphorus to make 220 match sticks and enough iron to make a 7.5 cm nail.
4.Speed of your sneeze-
Sneezing is the phenomenon by which foreign particles are expelled out through our nose.Sneezes can travel up to 160km/hr which is as fast as an express train.
5.Which part of your body is completely devoid of blood?
I know that 90% of you would tell that the answer is bones.And in that way,90% of you would be classic example of half-knowing idiots.For the smarter 10%,bones are the very place where red blood cells originate(remember the bone marrow!!).The correct answer is inner ear.The inner ear contains sensitive nerve receptors which pick up sound impulses.If there were arteries or veins in the inner ear,we would constantly hear the deafening sound of our heart pumping.Life would have been hell that way.
6.Which is the most abundant element in our body?
Even kids know that 70% of our body is water.What kids do not know is what is the most abundant element in our body.Well let the adults answer!!
Thinking of hydrogen?Forget it.The most abundant element in our body is oxygen.An adult's body of 70kg would have 43 kg of oxygen and only 7 kg of hydrogen.
7.Your heart and your blood-

Your heart pumps 13640 liters of blood everyday,enough to fill 40000 beer bottles.The blood travels along 100000 km of blood vessels,which is 2.5 times the distance round the equator. The red cells are the  primary component of the blood other than water.Red cells are destroyed at an amazing rate of 2-3 million per second.
8.Within you is a speed faster than a bullet train- 
There are 13000000000000 nerve cells in our body and they transmit messages at 290 km/hr.Nerve cells are the most important cells as they can control almost any function of our body.The nerve cells can be as large as 1 meter in length in case of an elephant.
9.Which is longer,the small intestine or the large intestine?
Thinking that the name tells it all.Beware names can be deceptive as in this case.The large intestine is only 1.5 meter long while the small intestine is about 5 meter long.It is because the large intestine is more in diameter that it is given the name.
10.Did you know that the cause of 80% of the dust in your house is you?
Getting dressed or undressed,rubbing parts of body together and other activities cause skin flakes to fall off.They fall at the rate of 50000 per minute.In your lifetime,you would shed 18 kg of skin.80% of your household dust are these skin flakes.
