Facts about our body |
||
|
• Our heart beats around 100,000 times every day.
• Our blood is on a 60,000-mile journey. • Our eyes can distinguish up to one million color surfaces and take in more information than the largest telescope known to man. • Our lungs inhale over two million liters of air every day, without even thinking. They are large enough to cover a tennis court. • Our hearing is so sensitive it can distinguish between hundreds of thousands of different sounds. • Our sense of touch is more refined than any device ever created. • Our brain is more complex than the most powerful computer and has over 100 billion nerve cells. • We give birth to 100 billion red cells every day. • When we touch something, we send a message to our brain at 124 mph. • We have over 600 muscles. • We exercise at least 30 muscles when we smile. • We are about 70 percent water. • We make one liter of saliva a day. • Our nose is our personal air-conditioning system: it warms cold air, cools hot air and filters impurities. • In one square inch of our hand we have nine feet of blood vessels, 600 pain sensors, 9000 nerve endings, 36 heat sensors and 75 pressure sensors. |
