Heart and blood vessel we
So the influence of the heart and blood vessel in our survival. Every human being needs oxygen to breathe and for the formation of energy in the body, and that oxygen may not work automatically in the body that we have no control or provide work in our bodies. To take over the heart is working, the provide oxygen overlooks the body and clean the body's metabolism of carbon dioxide.
Perform its duties in the heart by using the blood, the lack of blood is collected and pumped oxygen into the lungs, where blood will take the oxygen and expel carbon dioxide.

Of course, the heart does not work alone, he is assisted by a blood vessel attached to the body, the arterial blood vessel of a red blood vessel and the vena blue similar to the inky blue pen. The second blood vessel such as this do not change the main stream of water, but different. If you bring arterial blood from the body while the heart overlooks vena carry blood back to heart. Because this is the blood in our bodies can do with good circulation.
It is interesting that we need to know if in fact the small arterial and arteriol it was muscular, so adjust the diameter to increase or lowering of blood flow to certain areas while the vena diameter is usually greater than the arterial blood so that the vena haul with the same volume but in a lower speed and under pressure. Heart can manage its tasks with how well we do?
