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 right side of the heart is responsible for dealing with the deoxygenate blood, while the left side deals with oxygenated blood. Systemic Circulation is the process of carrying oxygenated blood to the body, while the Pulmonary Circulation is the process of carrying oxy-gen depleted blood from the heart to the lungs.
