liq [111]

Answer:

pulmonary circuit,  systemic circuit

Explanation:

The circulatory system consists of 2 circuits -

pulmonary circuit

systemic circuit.

In the lungs, the deoxygenated blood gets oxygenated and enters the left ventricle through pulmonary veins. The pureblood then passes into the left ventricle and then the ventricle pumps the oxygenated blood to different parts of the body. This blood passes to the body aways from the heart by aorta. When the blood gets deoxygenated, it again enters the right auricle. In this way, double circulation occurs and both types of blood do not mix together.
