The Miracle of Our Body

If you lined up all your veins and arteries end to end, they would stretch 70,000 miles. That’s long enough to wrap around the world three times.

The blood inside your body is actually blue. It turns red when it mixes with oxygen. That’s what happens when you cut yourself and bleed.When you sneeze, the air rushes out of your mouth at 100 miles per hour.

That’s as fast as the winds of a hurricane.When you are resting, the air you breathe passes through your nose at about four miles per hour. At this rate, you breathe more than 400 gallons of air every hour.

The average human body has 20 square feet of skin, 9,000 taste buds, 5 million hairs, and 13 billion nerve cells.The average human heart beats about 100,000 times every 24 hours.

During a 72-year lifetime, the heart beats more than 2.5 billion times.The blood of a human being makes a complete circuit of the body every 23 seconds.There are more signal connections in the human brain than there would be in a telephone exchange connecting everyone on earth.

We blink an average of 15,000 times a day, each one lasting roughly 1/10th of a second. That’s about an hour and 15 minutes each day we spend with our eyes partly or completely closed.
