Here are 10 miraculous things about your body that you take for granted.
1. Trillion is a lot when it started with one: Your body is made up of approximately 100 trillion cells. They all came from the division of one single cell. 300 million cells die every minute, but it’s really just a small fraction of the number we have. We produce 300 billion new cells every day and your body is constantly repairing and rebuilding.
2. Your brain is an amazing super-computer: The brain can hold five times as much information as the Encyclopedia Britannica. Nerve impulses travel at 270 kilometres per hour. The brain is comprised of 80% water. Oh, and it does all this on the same amount of power as a 10-watt light bulb.
3. Hair today…: Every day, the average person loses 60 -100 strands of hair. But there’s good news, we have to lose over 50% of our scalp hairs before anyone notices. Also, hair is virtually indestructible. Aside from flammability, human hair decays at such a slow rate that it is practically non-disintegrative.
4. Your heart works its heart out for you: The human heart beats about 100.00 times a day and creates enough pressure to squirt blood 10 meters. Such pressure is needed to pump blood through 10,000 kilometres of veins and capillaries, two and a half times the distance around the earth. The heart pumps 6 litres of blood, circulating three times every minute. In one day, your blood travels a total of 20,000 kilometres.
5. Your skin is the ultimate touch screen: Each square centimetre of your skin includes four meters of nerve fibres, 100 pain sensors, 200 nerve cells, 1400 nerve endings, 6 heat sensors, 12 pressure sensors, 15 sweat glands, 3 million cells, and 3 meters of blood vessels.
6. Your eyes alone are a study in genius: Our eyes can distinguish up to one million colour surfaces and take in more information than the largest telescope known to man. People blink once every four seconds. That’s because eyelashes act as windshield wipers, keeping dust and grime from getting into the eye itself.
7. The liver is a hardworking organ: Your liver works hard at over 400 functions, including detoxification, protein synthesis, and the production of biochemicals necessary for digestion. However, you could have two-thirds of your liver removed from trauma or surgery, and it would grow back to its original size in four weeks’ time.
8. Take a deep breath: Your lungs have a surface area the size of a tennis court. To oxygenate blood, our lungs are filled with thousands of microscopic capillaries. The large amount of surface area makes it easier for this to take place and get the oxygen where it needs to go.
9. Your disposable stomach lining: Your stomach gets a brand-new lining every four days. Strong digestive acids quickly dissolve the mucus-like cells lining the walls of the stomach. So, your body replaces them, routinely, before they are compromised.
10. No hiding from your fingerprints: Just three months into the pregnancy, an unborn child already has fingerprints. At just 6-13 weeks of development, the distinctive whorls have already developed. Interestingly, those fingerprints will never change throughout a person’s life. And your fingerprints are your own unique bar code indicating the true miracle you are!
