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.
Making the world better, one answer at a time. The up right chamber of heart known as the right atrium receives the deoxygenated blood from all over the body. This blood is then passes to the right ventricle through a tricuspid valve which is then sent to the lungs for oxygenation.aking the world better, one answer at a time.
