1 To find what your carâs fuel economy is (Metric System), multiply the amount of fuel used by 100 and divide that by the total kilometres driven. 2  Example: 42 litres x 100 / 400 = 10.5 litres / 100km.
There are four chambers of the heart: a right atrium, a right ventricle, a left atrium and a left ventricle. First, deoxygenated blood (blood without oxygen) is carried from the body through the Inferior and Superior Vena Cava. From these vessels, the blood is dumped into the Right Atrium of the heart.
The aorta carries oxygenated blood to the body. The pulmonary artery carries deoxygenated blood to the lungs and it is the only artery to carry deoxygenated blood. There are two veins associated with the heart.The vena cava, or great vein, carries deoxygenated blood back to the heart from the body.he pulmonary vein is the only vein to carry oxygenated blood which is on its way to the heart from the lungs. The diagram also shows you that the right and side of the heart, both atrium and ventricle, contains only deoxygenated blood.
