    capillaries and Veins. All arteries (with the exception of pulmonary and umbilical arteries) transport Oxygenated blood away from the heart to the rest of the body. They branch off into smaller structures named arterioles which lead to the Capillaries. In the capillaries the blood exchanges materials (e.g. o2 and CO2) with the tissue fluid of neighbouring cell. Afterwards the deoxygenated blood travels out of the capillary network, through the venules (smaller veins) and to the veins. The veins…

The red blood cells carry oxygen to all the muscles through the vein (carries blood to the heart). The veins have thin walls and contain blood under the low pressure. The arteries (carries blood away from the heart) have thick muscular walls and small passage ways. They contain blood under high pressure. The last blood vessels is…

    Venous return is the flow of blood back to the heart. This process is achieved by five mechanisms.

Gravity, but only when you are sitting or standing anywhere above the heart simple gravity is at work in returning blood back to the heart, not to say that very thing isn’t still working…
