INCREDIBLE FACTS ABOUT THE HUMAN BODY

Have you ever stopped to think about how amazing our bodies really are?  Here are some facts.  Invest in keeping your body as healthy as it can be so that it can continue to do what it does best.

v     Every muscle, organ and cell is controlled by your brain, which sends and receives signals through your nervous system.

v     Messages travel along the nerves as electrical impulses which can reach up to speeds of  248 mile per hour.

v     Except for your brain cells, 50,000,000 of the cells in your body will have died and been replaced with others, all while you have been reading this sentence.

v     There are 43 pairs of nerves that connect the central nervous system to every single part of the body. Twelve pairs go to and from the brain, and 31 go from the spinal cord. There are nearly 45 miles of nerves running through our body.

v     In one square inch of skin, there are four yards of nerve fibers, 1300 nerve cells, 100 sweat glands, 3 million cells and three yards of blood vessels.

v     There are more than 640 muscles, and they hardly ever work alone.

v     The adult heart beats about 40,000,000 times a year. In one hour the heart works hard enough to produce enough energy to raise almost one ton of weight one yard from the ground.

v     We have  5.6 liters (6 quarts) of blood which circulates through the body three times every minute. In one day, the blood travels a total of 19,000 km (12,000 miles)—which is about four times the distance across the US from coast to coast.

v     The amount of force used to squeeze a tennis ball is equivalent of the force your heart uses to pump blood throughout the body.  

v     Your stomach has to produce a new layer of mucus every 2 weeks otherwise it will digest itself.

v     The liver is often called the body's chemical factory. Scientists have counted over 500 liver functions.

v     Every part of the human body can repair itself—except a tooth.

v     Every human spent about half an hour as a single cell!

v   Your brain continues to send out electrical wave signals approximately 37 hours after death.

v About every seven years, your body replaces the equivalent of an entirely new skeleton.

v The spinal cord is less then two feet in length and is the same diameter as your index finger, yet it contains over 10 billion nerve cells.
