The Human Body Facts listed below are surely gonna blow your mind!!!
Blood
An adult
man’s body contains about 5 litres of blood. A woman’s body contains about 4.5
litres. The blood travels along 100,000 km of blood vessels, which is equal to
going 2.5 times round the equator. It contains 25,000,000,000 to 30,000,000,000
red cells. The life span of red cells is only about 120 days, and 1,200,000 to
20,000,000 of them are made every second. In a human lifetime you will make 0.5
tonne of red cells. Red cells are made and destroyed at a rate of 2-3 millions
per second.
Cells
There are 50 trillion cells in your body and 3
billion of them die every minute. Most of these are replaced. You have a total
of 1,000,000,000,000 white cells, which help fight germs and infections.
Digestive system
Your stomach produces up to 2 litres of hydrochloric
acid a day. Stomach acid is strong enough to dissolve metals, but it does not
damage the stomach linings because 500,000 cells are replaced every minute. The
small intestine is about 5m long and is the longest part of your digestive
system. The large intestine is a thick tube, but is only 1.5 m long.
Breathing
The average
person inhales 6 litres of air per minute or 8,640 litres a day. You take 13-17
breaths a minute when sitting and up to 80 during vigorous exercise. If you
average 20 breaths a minute, you breathe 28,800 times a day.
Brain power
You lose
100,000 brain cells every day! Luckily you have 100 billion altogether. If the
surface area of your brain could be ironed out it would measure 2,090 sq cm.
Heartbeat
Your heart pumps 13,460 litres of blood around your
body in a day, enough to fill 40,000 drink cans. An average heartbeat pumps 59 cc
of blood. An average heartbeat rate of 70 beats a minute adds up more than
100,000 beats a day.
Nerves
There are about 13,000,000,000,000 nerve cells in
your body, transmitting messages at speeds of 290 km/h as fast as the world’s
speediest road cars.
Sweat
 |
| Human Body |
You lose about 0.5 litres of water a day through 3000,000
sweat glands. In hot climates you may lose as much as 13.5 litres a day.
Urine
You will pass between
400 and 2000 millilitres of urine every day depending on how old you are, your
body size and the outside conditions, especially temperature.
Skin
Your skin weighs up to 4 kg and covers an area of up
to 1.3-1.7 sq m. Getting dressed and undressed, rubbing body parts together and
even breathing cause flakes of skin to fall of at a rate of 50,000 flakes a
minute. In a lifetime you will shed a total of 18 kg of skin. Up to 80% of house
dust is made up of dead human skin cells.
Chemicals
There is enough
carbon in your body to fill 900 pencils, enough fat to make 75 candles, enough
phosphorous to make 220 match heads and enough iron to make a 7.5 cm nail.
Sleep
In 7.5 hours of sleep, you will sleep lightly for
60% of the time and deeply sleep for 20%. You will dream for 20% of the time.
Skeleton
The human skeleton makes up about one fifth of a person's weight. An average adult weighing 70 kg will have a skeleton that weighs 14 kg.
Gas
On an average, a person will release 2 litres of gases from his intestines today as burps and farts.
Mouth
You will produce 37,800 litres of saliva in your
lifetime.
Nails
Your nails grow 0.05 cm a week, which is 4 times
faster than your toe nails.
Nose
Your sneezes can travel at a speed of 160km/h as
fast as a train.
Eyes
You blink about 20,000 times in a day.
Hair
Hair grows 0.5 mm every day.
