The double circulatory system of blood flow references two distinct and separate systems. [ This distinction is shared by most vertebrates to varying degrees to include amphibians, birds and mammals (including humans.) In contrast, fish have a single circulation system because they lack lungs. Most animals living above the water require a double circulatory system to allow the added benefit of direct oxygenation from a developed pulmonary circuit. Embryology of the human circulatory system is an advanced study of the double circulatory system as the distinction between the right and left portions of the heart is founded. For example, the adult human heart consists of two separated pumps or flow circuits. One side is dedicated to the right atrium and right ventricle (which pumps deoxygenated blood into the pulmonary circulation). This circuit is very low in pressure incumbent upon systemic resistance. The left circuit inclusive of the left atrium and ventricle (which pumps oxygenated blood into the systemic circulation) is better gated to high pressure. Blood in one circuit must go through the heart to enter the other circuit
