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.
Best Answer: Normally. Deoxygenated blood returns to the heart from the body, and the heart returns oxygenated blood to the body through the aorta. The only place where oxygenated blood would come *to* the heart is from the lungs. Since it goes to the heart, it must be a vein. So the answer is the pulmonary veins.
