Circulatory+system

The circulatory system makes the blood flow around your body so oxygen can reach all the body. This system consists on the [|heart], arteries, capillaries, and veins; which interact to complete on function, circulation. As your blood starts the process it leaves the heart from the left vertice and goes into the biggest artery in the body called the aorta. This blood is full of oxygen, this is important because oxygen makes the brain cells work and command the rest of the body. As it passes threw the body, it comes back through the veins at this point the blood is full of carbon dioxide, while it passes threw the lungs the waste product is replaced with fresh oxygen which is taken back to the heart.



[|Arteries and Veins] are increadibly important in this process. Arteries are strong, flexible tubes the carry blood rich in[| oxygen] out of the heart, the size can vary some being as thick as fingers and others as thin as hair, the thin arteries are called arterioles. The arterioles carry red blood witch is red because of the oxygen it carries. Veins carry the blood back to the heart, the blood they carry is not as bright as the one arteries carry because it is not so rich in oxygen, they also have thinner walls because the blood that comes back to the heart is not in so much pressure as the one that is carried out of the heart. For the [|oxygen] link, it is a page with lots of definitions oxygen is almost in the middle after organ. Here is an awesome picture showing us in the right body the arteries, and in the left body the veins.
