The human body is so complex a system that, despite thousands of years of medical knowledge and experience, it still continues to amaze doctors and researchers. That’s why many of us in our ordinary body part or function appears we may be hidden, even very interesting and unexpected things.
The only part of the body that has no blood supply is the cornea of the eye. It receives oxygen directly from the air. The human brain has a memory capacity which is the equivalent of more than four terabytes on a hard drive. The average human body contains enough sulphur to kill all the fleas on the average dog, enough carbon to make 900 pencils, enough potassium to fire a toy cannon, enough fat to make seven bars of soap and enough water to fill a 50-litre barrel.
The speed of nerve signals from the brain to the hour and can reach 273.6 km. How this information so react quickly to events occurring around us and we can explain how we feel the pain immediately.
knowledge of the human brain can store more than 5 times the amount of information in the Encyclopedia Britannica. Or the old square-Larousse’ta of us. Scientists have not determined a figure but it is thought to be between 3 and 1000 Terabytes of capacity. If 900 years of British History Archive is 70 Terabytes of thought, we are talking about an incredible capacity.
pressure created by the human heart, is sufficient to squirt blood 10 meters in height.
We feel that in our hearts at that. such a high pressure in order to distribute the blood and all body organs need a robust enough to withstand it.
Considering that the average size of your fist up of the human heart, the aorta diameter of the vein is pretty much (the outer diameter of a garden hose in the American standard of about 27 mm. D). The reason for this vessel is so large is that it distributes the main source of the body in terms of oxygen-rich blood.
