The energy produced that the human heart beats of every day, enough to raise the object weighing 9 kilograms 1 meter, scientist calculate people from born to 50 year old, energy that heart's beating for produce can send 100 satellite of heavyweight into the earth track.
Blood vessel length can wind the earth two and a half circle
The human body has been covered with close and numerous blood vessels, says that perhaps you do not believe to come out, human body blood vessel have more than 100 billion, answer first line into all blood vessels of the human body in all, the scientist estimates, the adult's total length of blood vessel is about 96000 kilometers. The earth is 40000 kilometers in one week,
That is to say human blood vessel connect after the one line, length can make a detour the earth 2 and a half circle.
The blood circulation only takes 20 seconds in one week
The energy produced that the human heart beats of every day, enough to raise the object weighing 9 kilograms 1 meter. The scientist calculates, when the person is from born to 50 years olding, the heart beat the energy produced could send the satellites of 100 drops of heavyweight into the earth track.
The blood that the heart gave out, through the main artery, hit the artery, arteriole, capillary on it flow get whole body, then it is through venule, in the intravenous with systemic vein, return heart again. The blood is according to this order " Travel " ,Very fast, circulate a circle to only need 20 seconds in the body, the tempo is calculated according to this, the blood can circulate 180 circles within an hour, is 1,576,800 circles in one year, if live to the age of 80 alone, the blood will circulate 126,144,000 circles in the body.
4 that the intestines length is the height- 5 times
How long on earth is the intestines? The stomach department's doctor says, different positions, the length is different, dissect the digital display measured to the human body, 60 centimetres of duodenums, the length of small intestine can be up to 6.7 meters, the length of large intestine is 1.5 meters. The anatomist thinks, the length of everybody's intestines is all different, is generally about 4 to 5 times of the height.
2,500 million to 3 billion times of heartbeat of all one's life
The scientist finds, tortoise's life-span can be as long as 177 years, because there are only 6 times in its heartbeat of every minute, the heart beats about 560 million times in all one's life. Surprisingly, except the mankind, the number of times of heartbeat of all one's life of mammals is basically the same, it is probably about 730 million times, and person's number of times of total heartbeat of all one's life is about 2,500 million to 3 billion times.
