info-pictogram1 This is the blood vessel network of the human face.

There are three varieties of blood vessels: arteriesveins, and capillaries. During blood circulation, the arteries carry blood away from the heart. The capillaries connect the arteries to veins. Finally, the veins carry the blood back to the heart.

If you took all of the blood vessels out of an average child, and laid them out in one line, the line would be over 60,000 miles long! An adult’s vessels would be closer to 100,000 miles long!

Besides circulating blood, the blood vessels provide two important means of measuring vital health statistics: pulse and blood pressure. We measure heart rate, or pulse, by touching an artery. The rhythmic contraction of the artery keeps pace with the beat of the heart. Since an artery is near the surface of the skin, while the heart is deeply protected, we can easily touch the artery and get an accurate measure of the heart’s pulse.

About Akhi Soufyan

If you see goodness from me, then that goodness is from The Creator. You should be thankful to The Creator for all of that. Cause I'm not the architect of that. I'm only the...the recipient. If you see weakness or shortcoming in me it's from my own weakness or shortcoming. And I ask The Creator and the people to forgive me for that. _______________________________ Website eigenaar voor een betere wereld en doel, niet gericht op verdiensten van geld maar goede daden. In de naam van Allah, de Barmhartige. Als je goedheid van mij ziet, dan is dat de goedheid van de Schepper (God). Wees De Schepper dankbaar voor dat. Want ik ben daar niet de architect van, ik ben alleen de ontvanger.
